摘要：
A voltage mode logic device based on RF-Field-driven DC-SQUID (RFDS) using high-TC superconducting Josephson junctions has been proposed. RFDS produces large RF-induced steps, and the orders of steps are strongly selected by DC magnetic flux crossing the SQUID loop superposing with RF magnetic field. In this paper, we present the experimental results of RFDS fabricated by using YBCO grain boundary Josephson junctions. The results are evaluated with numerical simulations. The enhancement of RF-induced steps, the strong selection of step orders and the switching performance are demonstrated.
