摘要:
随着通信技术的发展,HEMT器件的栅长变得越来越短,而早期的速度-场经验公式随着栅长的不断减小已不能精确地描述这种变化.通过对现有的速度-场经验公式的计算机模拟仿真,发现其与实测的文献数据之间存在一定的误差,因而提出一种改进的速度-场经验公式.在线性电荷控制模型的基础上,考虑沟道长度调制效应,解析出一种新的高电子迁移率晶体管(HEMT)Ⅰ-Ⅴ模型.仿真结果表明,该模型具有较高的精度.
Abstract:
With the development of communication technology, the gate length of HEMT devices becomes shorter and shorter, and the early speed-field empirical formula can no longer accurately describe this change as the gate length continues to decrease. Through the computer simulation of the existing velocity-field empirical formula, it is found that there is a certain error between it and the measured literature data, so an improved velocity-field empirical formula is proposed. Based on the linear charge control model, a new high-electron mobility transistor (HEMT) I.-V. model is analyzed by considering the channel length modulation effect. The simulation results show that the model has high accuracy.
