中文摘要

本文提出了一种与GaN功率HEMT单片集成的栅极静电放电(ESD)保护电路。该多功能电路不仅增强了栅极的ESD鲁棒性,还在功率HEMT正常开关操作期间提高了导通电阻(RON)和阈值电压(VTH)的稳定性。

English Abstract

This work presents a gate electrostatic discharge (ESD) protection circuit monolithically integrated with the GaN power high-electron-mobility-transistor (HEMT). In addition to enhancing the gate robustness against the ESD event, this multifunctional circuit also improves the stability of on-resistance (RON) and threshold voltage (VTH) when power HEMT is under normal switching operations. Such imp...
