AlNGaN HEMT T-gate Optimal Design
The GaN HEMT is widely used in high-frequency aspects,use the T-gate to reduce gate resistance is one of the most effective methods to improve the the device maximum oscillation frequency (fmax).But fmax is very sensitive to T-gate size,improper selection may reduce fmax,Therefore,in order to reduce the cost of production,it is necessary to select appropriate simulation T-gate size.We have worked out AlGaN/GaN HEMT with gate length of 0.17μm and fmax values 110GHz.Accuracy of the simulation model is verified by experiment.Then detailed simulates the impact of the T-gate size and we obtain ptimized T-gate size range.
