GATE DRIVERS AND AUTO-ZERO COMPARATORS

Abstract:

Gate drivers and auto-zero comparators are disclosed. An example integrated circuit includes a transistor comprising a gate terminal and a current terminal, a gallium nitride (GaN) gate driver coupled to the gate terminal, the GaN gate driver configured to adjust operation of the transistor, and an enhancement mode GaN comparator coupled to at least one of the transistor the GaN gate driver, the enhancement mode GaN comparator configured to compare a voltage to a reference voltage, the voltage based on current from the current terminal, the GaN gate driver configured to adjust the operation of the transistor based on the comparison.
