摘　　要：研制成的在常温下工作的谐振隧穿二极管 (RTD) ,峰谷比达到了 5∶ 1,最高振荡频率为 2 6 .3GHz.采用基于物理意义的电流 -电压方程 ,利用通用电路模拟软件 PSPICE,建立了其直流电路模型 ,模拟结果和实验数据吻合得很好 ;并以此为基础模拟出了以 RTD为驱动器 ,以电阻或 RTD本身为负载的电路双稳态特性 ,同时分析了 RTD器件双稳态特性 .A Resonant Tunneling Diode working at roon temperature is briefly described,which has PVCR of 5∶1,and cutoff frequency of 26 6GHz.Using the physics-based RTD current-voltage equation,a DC circuit model of the Resonant Tunneling Diode with PSPICE software is established.The simulation results agree with the experimental data very well.A circuit,in which the RTD works as a driver and the resistor or the RTD works as load,is also simulated.The bistable characteristics are obtained and analyzed in details.
