A Monolithic Integrated Logic Circuit of Resonant Tunneling Diodes and a HEMT
【摘要】 介绍了一种基于共振隧穿二极管(RTD)和高电子迁移率晶体管(HEMT)的单片集成电路.采用分子束外延技术在GaAs底层上重叠生长了RTD和HEMT结构.RTD室温下的峰谷电流比为5.2∶1,峰值电流密度为22.5kA/cm2.HEMT采用1μm栅长,阈值电压为-1V.设计电路称为单稳态-双稳态转换逻辑单元(MOBILE).实验结果显示了该电路逻辑运行成功,运行频率可达2GHz以上.
【Abstract】 A technology for the monolithic integration of resonant tunneling diodes (RTDs) and high electron mobility transistors (HEMTs) is developed.Molecular beam epitaxy is used to grow an RTD on a HEMT structure on GaAs substrate.The RTD has a room temperature peak-to-valley ratio of 5.2∶1 with a peak current density of 22.5kA/cm2.The HEMT has a 1μm gate length with a-1V threshold voltage.A logic circuit called a monostable-to-bistable transition logic element (MOBILE) circuit is developed.The experimental result confirms that the fabricated logic circuit operates successfully with frequency operations of up to 2GHz.
