1. PWM and driver start discharging CGS to the MOSFET turnoff plateau. 2. At the VGS plateau, the VDS begins to rise from ground. During the rise time of VDS, the positive dV/dt of the drain generates a current flowing through CGD that opposes the current from the gate-driver circuit,...

Their effects can be investigated together with the external parasitic components usually associated with layout and with accompanying external circuit elements like leakage inductance, a current sense resistor, and so forth. For completeness, the external series gate resistor and the MOSFET driver's ...
The common functions of MOSFET gate circuits are as follows: 1. Remove the noise coupled into the circuit and improve the reliability of the system; 2. Accelerate the conduction of MOSFET and reduce conduction loss; 3. Accelerate the turn-off of the MOSFET and reduce the turn-off loss; 4...
