ã€Abstractã€‘ The Josephson junction device was packaged with PSpice, and the equivalent circuit models of DC-SQUID and RF-SQUID were respectively constructed in the Advanced Design System(ADS).The typical response curves of DC-SQUID were simulated, the typical hysteresis response characteristics of RF-SQUID were simulated and the simulation results agreed with the theoretical analysis. It is the first time to simulate and verify the characteristics of SQUID in ADS, which enriches the simulation ways of superconducting Josephson junction devices and provides convenience for parameter adjustment during SQUID device design.æ›´å¤š è¿˜åŽŸ
