摘　　要：RTD与HBT是高频高速器件,共振隧穿二极管-异质结晶体管(RTD-HBT)环形振荡器有很好的应用前景。详细介绍了RTD-HBT高速低功耗环形振荡器的工作原理,建立了RTD,HBT及RTD-HBT环形振荡器的等效电路模型,并对RTD-HBT环形振荡器用Pspice模拟软件进行了电路模拟。模拟结果与预期结果一致,有助于指导该电路的设计。RTD and HBT are devices with advantages of high frequency and high speed, RTD-HBT ring oscillator has a great potential for future application. The principle of a ring oscillator using RTD-HBT （resonant tunneling diode-heterejunction bipolar transistor） heterestructure for high-speed and low-power applications was introduced. The equal circuit models of RTD, HBT, RTD-HBT ring oscillator were established. The ring oscillator was simulated with Pspice. The simulation results are consistent with the expectation results, and it contributes to the design.
