摘要: 创新地开展p型栅GaN器件的单粒子辐照与建模研究,提取的单粒子激励电流首次被加载用于全GaN的低压差线性稳压器(LDO)稳压电路的单粒子设计中,获得了该电路单粒子敏感节点,最终得到该节点在重载状态与轻载状态时对应的单粒子瞬态(SET)响应分别为500 mV/60 ns,1210 mV/60 ns。上述研究建立起GaN器件-全GaN基电路的T-CAD/SPICE单粒子效应协同设计方法。

Abstract: Single event irradiation and modeling of p-gate GaN devices are innovatively carried out. The extracted single event excitation current is used for the first time into the single event design of a full GaN low dropout regulator (LDO) voltage stabilizing circuit, and a single event sensitive node of the circuit is obtained. The single event transient (SET) responses of the node corresponding to the heavy load state and the light load state are 500 mV/60 ns and 1210 mV/60 ns respectively. The above study establishes a T-CAD/SPICE single event effect collaborative design method for GaN devices and all GaN based circuits.

Key words: GaN irradiation effect, GaN LDO, radiation hardening, p-gate GaN device
