【Abstract】 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.更多还原
