An active gate driver provided to drive a power transistor includes a two-level Miller plateau detector, a cycle shifter, a flexible split-path feedback circuit, a PMOS switch picker, a NMOS switch picker, a PMOS buffer array and a NMOS buffer array. The active gate driver turns off some PMOS transistors of the PMOS buffer array and some NMOS transistors of the NMOS buffer array to lower power consumption when the power transistor in the Miller plateau. And the active gate driver also turns off some PMOS transistors of the PMOS buffer array if a gate-source voltage is greater than a high-potential reference voltage, thereby further reducing power consumption.
An active gate driver configured to drive a power transistor comprising:
