提出了谐振隧道二极管 (RTD) 中量子电容紧凑模型形式的简单推导。量子电容被证明可以降低电阻截止频率。描述了模型在 SPICE 中的实现。 SPICE 仿真演示了强非线性量子电容对振荡器电路的失真效应。当 RTD 电容与电路其余部分的电容相当时，非线性对于最高频率应用变得很重要。
A simple derivation of the form for the compact model of the quantum capacitance in a resonant tunneling diode (RTD) is presented. The quantum capacitance is shown to reduce the resistive cutoff frequency. The implementation of the model into SPICE is described. The distorting effect of the strongly nonlinear quantum capacitance on an oscillator circuit is demonstrated in a SPICE simulation. The nonlinearity becomes important for the highest frequency applications when the RTD capacitance is comparable to the capacitance in the rest of the circuit.
