In order to obtain better high frequency performance for GaN-based devices, we investigate the influence of the gate length Lg, the gate-source space Lgs, the gate-drain space Lgd, and the thickness of barrier AlGaN on frequency performance of AlGaN/GaN high electron mobility transistors (HEMTs) using silvaco TCAD simulation. Besides, the importance of Ohmic contact resistance Rc to current-gain cutoff...
In this paper we propose a design with low-power and distance tracking for both a remote control board and a monitor board for an MP3 player. The design consists of a microprocessor, a GPS module, an RF module, 6 tyco switches and a 2times16 LCD display enabling the user to use all functions. Our remote control board supports the function key of a typical MP3 player with 27 functions. In addition...
