Answer :

MOSFET gate drive circuit:

The turning on and turning off of MOSFET can be controlled from gate to source voltage signal. If the gate to source voltage of MOSFET exceeds threshold voltage it turns on the MOSFET. MOSFET is a voltage controlled device. MOSFET have high input impedance. There are two configurations for gate drive circuit one is simple MOSFET gate drive circuit and second is totem pole configuration gate drive circuit for MOSFET.
