Simulation method of transmission-type Radio-Frequency Single-Electron Transistor (RF-SET) by SPICE

An efficient simulation method for transmission-type radio-frequency single-electron transistors (RF-SETs) is developed. By introducing equivalent circuits of propagating microwaves through RF cables, we solve the master equation for RF-SETs self-consistently by using the conventional circuit simulator SPICE including the SET current model. By examining transmitted waves from the transmission-type RF-SET, we show that the developed method successfully reproduces the numerical reference methods (calculated self-consistently). We also show that our method provides simple and fast ways to simulate the RF-SETs even under complicated circuit geometry and in high frequencies over GHz.
