Miller effect of MOS switching on
1. In the first stage of MOS tube opening process, Vgs starts to rise, and Vds and Id remain unchanged. In this stage, the driving current charges the gate capacitor Cgs until Vgs reaches the threshold Vgs (th). In this stage, MOS tube is in the cut-off zone. In the second stage, the MOS tube starts to conduct, and the Id starts to have current and gradually increases. In the current growth range, the Id reaches the maximum current, and the Vds decreases slightly, because
