Abstract

This letter presents a monolithic integrated circuit (IC) platform based on the p-GaN gated HEMT technology with a hydrogen plasma treatment (H-treated) process. A 48 V DC-DC power conversion at a switching frequency of 1 MHz is realized. The peripheral enhancement/depletion (E/D-) mode devices formed circuit components, and monolithically integrated with the power device. This is the first H-treated p-GaN platform for the monolithic GaN mixed-signal power IC, the D-mode device will employ the H-treated p-GaN layer as the gate dielectric, with no additional insulator layer. The corresponding ASM-HEMT models have been calibrated for the computer-aided circuit design. Excellent agreement between simulation and static/dynamic experimental results have also been verified with inverters and comparators.

氢等离子体处理 p-GaN 栅极 HEMT 集成用于直流-直流转换器

本文介绍了一种基于氢等离子处理（H-treated）工艺的 p-GaN 门控 HEMT 技术的单片集成电路（IC）平台。实现了开关频率为 1 MHz 的 48 V DC-DC 电源转换。外围增强/耗尽（E/D-）模式器件形成电路元件，并与功率器件单片集成。这是首个用于单片 GaN 混合信号功率集成电路的 H 处理 p-GaN 平台，D 模器件将采用 H 处理 p-GaN 层作为栅极电介质，不需要额外的绝缘层。相应的 ASM-HEMT 模型已为计算机辅助电路设计进行了校准。模拟与静态/动态实验结果之间的出色一致性也已通过逆变器和比较器得到验证。
