Keywords:DCbiasSaturationfluxdensityConstantpermeance 1 Introduction Common filter inductance mainly includes common mode filter inductance, differential mode filter inductance and rectifier filter inductance. The first two inductors are mainly used for various line filters and work under AC conditions. The latter is used to filter out the AC ripple after rectification, so that the DC part after rectification is more straight. Because it works under DC condition, the influence of DC magnetization on inductance has to be considered. In the past, electronic equipment, such as those using electronic tubes, mostly used high voltage and small current for rectification output, while today's electronic equipment using transistors and integrated circuits, mostly used low voltage and large current. Since the DC magnetization force is proportional to the current, more attention should be paid to the influence of DC magnetization on inductance. This requires that the filter inductance must be suitable for high current conditions. Therefore, what kind of material is selected as the core. How to design a good filter coil, reduce the influence of DC magnetization and prevent the saturation of the magnetic core has become a problem worthy of attention. 2. Characteristics of constant magnetic conductivity or constant inductance The rectifier filter inductance works under the condition of high DC current

Challenges faced by electronic circuit CAD in high-frequency circuit analysis As the operating frequency of RF circuits continues to increase, the performance characteristics of chip inductors in application have changed significantly, and they have begun to show the operating characteristics of low-end microwave bands. Therefore, in order to effectively improve the electrical parameters of chip inductors and improve the performance of RF circuits, it is necessary to further analyze the different laws of their low-frequency characteristics and high-frequency characteristics. On the other hand, the constant introduction of new communication systems (GSM, CDMA, PCS, 3G...) has made the chip inductor work at 2GHz or even higher. Therefore, the traditional lumped parameter circuit theory is used to Inductor The impedance analysis of components shows more and more obvious limitations. Impedance ground analysis: the physical meaning of inductance is that the conductive coil is used to store the energy of alternating magnetic field, Inductor The main function of the component is to provide the required inductive impedance to the circuit and complete the corresponding circuit functions (matching, filtering, oscillation, etc.) in cooperation with other related components. Common chip Inductor The components include laminated chip, wound chip, photolithographic film and other forms, and their production processes and internal electrode structures are different. However, at medium and low frequencies, because the signal wave is longer than the device size, the circuit response of the device is less affected by the internal electrode structure, and the lumped parameter equivalent model can usually be used to approximate the impedance characteristics of chip inductors. Based on this, the functional expressions of common electrical performance parameters can be derived. Admittance function Y (j)=（ {1}over {R_{O}}+ {r}over {r^{2}+ ^ {2}L ^ {2}_ {O}})+j( C_ {O}- { L_{O}}over{r^{2}+ ^ {2}L ^ {2}_ {o} }) then impedance function Z (j)= {1}over {Y (j)}=R()+j() can approximate the derived impedance Z ()=sqrt {R ^ {2} ()+^ {2} ()}={L_ {O}} over sqrt {({L_ {O}} over {R_ {O}}}}+ {r}over { L_{O}})^{2}+(1-

For example, LGX represents a small high-frequency inductive coil, and LG1 represents a horizontal high-frequency inductive coil. 3. Main technical parameters and identification method (1) Inductance L. The inductance of the coil L is also called self inductance coefficient or self inductance, which is a physical quantity indicating the self inductance of the coil. Its units are Heng (H), milli Heng (mH) and micro Heng (¨ H). (2) Quality factor Q. The quality factor of the coil is also called the quality factor, which is a physical quantity representing the quality of the coil. It refers to the ratio of inductance (∞ L) and equivalent loss resistance R of the coil when it operates at a certain frequency and AC voltage. That is, when o=poison=device frequency is low, it can be considered that R is equal to the DC resistance of the coil; When the frequency is high, R is the total equivalent resistance including various losses. (3) Distributed capacitance. The capacitance between turns of the coil, between the coil and the shield (when there is a shield), between the coil and the magnetic core, and between the base plate is called distributed capacitance. The existence of distributed capacitance reduces the Q value of the coil and makes the stability worse. Therefore, the smaller the distributed capacitance of the coil, the better. 4． Inductor Parameter identification (1) For inductance coil with large volume, its inductance and nominal current are marked on the enclosure.

This induced electromotive force will block the change of current and convert part of electric energy into magnetic energy for storage in Inductor Medium. Self inductance can be described by a parameter, called inductance, in Henry. 2. Current voltage relationship: Inductor There is a specific relationship between current and voltage in. According to Ohm's law, Inductor The relationship between the voltage and the current passing through it can be expressed by the following formula: V=L * di/dt where V is Inductor L represents inductance, and di/dt represents change rate of current. This formula shows that when the current changes, Inductor Will generate voltage, which is the same as Inductor And the rate of current change. 3.

Inductive sensor is a common type of sensor, which is often used to measure the position, distance, speed and other information of objects. When DRV8816PWPR inductive sensor is used for detection, there are some places that are easy to be ignored, so as to ensure the accuracy and stability of detection. 1. Environmental interference: Inductive sensors are vulnerable to the impact of the external environment, such as other electromagnetic interference, the presence of metal or conductive objects, etc., which may interfere with the detection results of sensors. Therefore, when installing and using inductive sensors, it is necessary to minimize the impact of these environmental factors, such as avoiding areas with strong magnetic fields and reducing the number of metal objects. 2. Temperature impact: temperature change will affect the performance of inductive sensor, resulting in instability of output signal. Especially for some low-cost inductive sensors, their internal components are easily affected by temperature. Therefore, when using inductive sensors, temperature compensation or other measures should be considered to reduce the impact of temperature on sensor performance. 3. Interaction between coils: some inductance sensors are composed of multiple coils, and the interaction between coils is also a problem that is easy to be ignored. For example, the magnetic coupling effect and mutual inductance effect between coils may lead to the distortion of the output signal. Therefore, when designing and using inductive sensors, it is necessary to fully consider the interaction between coils and take corresponding measures to reduce this impact. 4. Supply voltage fluctuation: the working performance of inductance sensor is often affected by the supply voltage. If there is fluctuation or noise in the supply voltage, it will directly affect the output signal of the inductive sensor. Therefore, when using inductive sensors, it is necessary to ensure the stability of the supply voltage to avoid the impact of voltage fluctuations on the sensor performance. To sum up, the inductive sensor needs to pay attention to environmental interference, temperature influence, interaction between coils, power supply voltage fluctuation and other factors in the detection process to ensure the normal operation and accurate detection of the sensor. In practical application, the influence of these problems can be minimized by reasonable design, installation and calibration, so as to improve the reliability and stability of inductive sensors.

In amplifier, capacitance and Inductor Components are commonly used components, they play an important role in the circuit. However, these two components will also produce noise in the amplifier, which will have a certain impact on the performance of ATTINY13A-SSU amplifier. Capacitance and Inductor The noise problem of components in the amplifier. As a charge storage device, capacitors are often used in coupling and filtering circuits of amplifiers. In the coupling circuit of the amplifier, the capacitor is used to isolate the input signal from the DC bias voltage of the amplifier, so as to ensure that the amplifier works at an appropriate working point. In the filter circuit, the capacitor is used to weaken or remove the high-frequency noise or stray signal in the amplifier output signal to obtain a clean output signal. Inductor As a component for storing magnetic energy, it is often used in coupling and filtering circuits of amplifiers. In the coupling circuit, Inductor It is used to isolate the input signal from the DC bias voltage of the amplifier, so as to ensure that the amplifier works at a suitable working point. In the filter circuit, Inductor It is used to weaken or remove the low-frequency noise or stray signal in the amplifier output signal to obtain a clean output signal. However, capacitance and Inductor The component itself will also introduce some noise. The main noise sources of capacitors are dielectric loss and resistance.

Inductor The main noise source is the coil resistance and eddy current loss. The resistance of the coil will be introduced Inductor And eddy current loss will cause Inductor Magnetic field noise is generated internally.

Inductor And capacitors are common passive components in circuits, they play an important role in high-frequency circuits. Understanding their high-frequency characteristics is very important for designing and analyzing high-frequency circuits. This article will introduce Inductor And capacitor high frequency characteristics, including impedance and resonance. Inductor The impedance in the high-frequency circuit is mainly composed of its inductive reactance and resistance. Inductive reactance is Inductor The impedance of the AC signal is proportional to the frequency. The calculation formula of inductance is: Xl=2 π fL, where Xl is inductance, f is frequency, and L is inductance. Inductor The inductance increases with the increase of frequency, which means that at high frequencies, Inductor The stronger the resistance to current. This is because at high frequencies, the current changes direction with time, Inductor It will generate induced electromotive force, making it difficult for current to pass through. Therefore, in the high-frequency circuit, AD8032ARZ Inductor It is often used as a component to block the flow of high-frequency signals. In addition to sensitivity, Inductor There is also a resistance component called DC resistance or AC resistance. Inductor The resistance of is mainly from the resistance of the coil and the resistance of the wire. At high frequencies, Inductor The resistance of the wire will increase with the increase of frequency, because the resistance of the wire will increase with the increase of frequency, and the coil will also have additional resistance due to eddy current effect. The impedance of capacitor in high-frequency circuit is mainly composed of its capacitive reactance and resistance. Capacitive reactance is the impedance of capacitor to AC signal, which is inversely proportional to frequency. The calculation formula of capacitive reactance is: Xc=1/(2 π fC), where Xc is the capacitive reactance, f is the frequency, and C is the capacitance. The capacitive reactance of the capacitor decreases with the increase of frequency, which means that the impedance of the capacitor to the current is smaller at high frequency. This is because the capacitor can store charge and can charge and discharge with the change of current at high frequency. Therefore, in high-frequency circuits, capacitors are often used as components for passing high-frequency signals. In addition to capacitive reactance, capacitors also have a resistance component called DC resistance or AC resistance. The resistance of capacitor mainly comes from the resistance of dielectric and electrode. At high frequency, the resistance of capacitor will increase with the increase of frequency, because the resistance of dielectric increases with the increase of frequency, and the electrode also

TPS6303x devices provide power supply solutions for products powered by two or three alkaline, NiCd or NiMH batteries, or one lithium-ion or lithium polymer battery. When using a single lithium-ion or lithium polymer battery, the output current may be as high as 600 mA, and then discharge it to 2.5 V or less. The buck boost converter is based on a fixed frequency, pulse width modulation (PWM) controller using synchronous rectification to achieve maximum efficiency. Under low load current, the converter enters the energy-saving mode to maintain high efficiency in a wide range of load current. Energy saving mode can be disabled to force the converter to operate at a fixed switching frequency. The maximum average current in the switch is limited to a typical value of 1000 mA. The output voltage can be programmed using an external resistance voltage divider or internally fixed on the chip. You can disable the converter to minimize battery consumption. During the shutdown, the load is disconnected from the battery. The TPS6303x device operates in the free air temperature range of – 40 ° C to 85 ° C. The device is packaged with 10 pin VSON, and the size is 2.5mm × 2.5mm (DSK). Input voltage range: 1.8 V to 5.5 V Fixed and adjustable output voltage options, range: 1.2 V to 5.5 V Efficiency up to 96% Output current 800 mA at 3.3 V in step-down mode (VIN=3.6 V to 5.5 V) Output current up to 500 mA at 3.3 V in step-up mode (VIN>2.4 V) Static current of automatic converter between step-down and step-up modes is less than 50 μ A power saving mode can improve efficiency at low output power. It can force the load to be disconnected during fixed frequency operation and synchronous shutdown. Overheat protection adopts small 2.5mm × 2.5mm 10 pin VSON package (QFN)
