The purpose of the project aims to develop high frequency power integrated circuits and thereafter applications of power modules based on fully GaN-based process, which includes enhancement-mode GaN, depletion-mode GaN, and power GaN devices while utilization of the special properties of high-voltage stress as well as high-speed switching characteristics of GaN.The overall program is divided into four years. In the first year, we will design a fully integrated gallium nitride-based low-side driver, consisting of a voltage regulator circuit, over-voltage/over-current protection circuit, high-speed comparator circuit, PWM driver, and an oscillation suppression circuit. The work in the second year will develop a high-frequency high-speed power factor correction module and a high-frequency isolated charger module, respectively, based on the GaN-based high speed low-side driver developed in the first year. In the third year, we plan to design an all-gallium nitride-based integrated half-bridge driver. In addition to optimize the sub-circuit modules required for the low-side driver, we also develop high-side drivers, including high-speed level shifters, bootstrapped drivers and a non-overlapping protection circuit. In the fourth year, a high-frequency non-isolated step-down LED driver module, a high frequency full bridge audio amplifier module and a wideband envelope tracking amplifier will be designed and demonstrated based on the half-bridge integrated driver developed in the third year. In addition to be utilized in the high-speed switching power converters that are indispensable for various electronic products and their terminal applications, the fully gallium-based driver circuit developed in this project is also expected to meet the requirements of green energy technologies as well as the modern trends towards small form factor and light weight. The outcome of the projects provides high-speed power integrated circuit design paradigm for both high-efficiency voltage converters and power inverters, which can be widely used in a variety of high-end power circuits and engineering systems.
