摘要
设计并研制了共振隧穿二极管(RTD)与异质结双极晶体管(HBT)单片集成负阻逻辑单元。详细介绍了逻辑单元的材料结构及工艺流程的设计过程,得到了较好的负阻特性,其开启电压1V左右,峰谷比大于2∶1。同时建立了负阻逻辑单元的模型,通过Pspice模拟结果表明与实际逻辑单元特性吻合良好。
We designed and made a monolithic integrated negative resistance logic unit, which is composed of resonant tunneling diodes(RTD) and heterojunction bipolar transistors (HBT). The material structure and technological process design of the logic unit is introduced in detail. A good characteristic is obtained with turn-on voltage of 1 V and peak-to-valley current ratio of more than 2 : 1. Meanwhile, the circuit model of negative resistance logic unit is established. The simulation results using PESPICE software of the logic unit agree with the characteristics of the real logic unit very well.
