A circuit for increasing the voltage/current level of a signal to drive a power transistor from a low voltage input. The gate drive circuit comprises a voltage multiplier for increasing the voltage level of a low voltage input signal, a level shifter for shifting the voltage level of a logic signal to a level relative to a voltage signal produced by the voltage multiplier, and a source follower, connected to the level shifter, for increasing the current of the increased voltage, level shifted output signal of the level shifter. The resulting multiplied, shifted, and increased current signal can be used to drive a power transistor.
