We demonstrate the key module of comparators in GaN ICs,based on resistor-transistor logic(RTL)on E-mode wafers in this work.The fundamental inverters in the comparator consist of a p-GaN gate HEMT and a 2DEG resistor...
This paper proposes a high-performance pulse-width modulation(PWM) AC/DC controller, which can drive a high-voltage(HV) 650-V power metal-oxide-semiconductor field-effect Transistor(MOSFET) in typical applicatio...
