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 .
The resonant tunneling diode (RTD) developed at room temperature has a peak to valley ratio of 5: 1 and a maximum oscillation frequency of 26.3 GHz. Based on the current-voltage equation based on physics, a universal circuit simulation software PSPICE , The DC circuit model is established and the simulation results are in good agreement with the experimental data. Based on this, the bistable characteristics of the circuit with RTD as the driver and the resistance or the RTD itself as the load are simulated, and the RTD device Bistable characteristics.
