We explore bi-superconducting quantum interference device (bi-SQUID) designs suitable for the fabrication process of high-temperature superconducting step-edge Josephson junctions. The bi-SQUID offers increased linearity and improved signal detection performance over a SQUID. The realization of high-temperature superconducting (HTS) bi-SQUIDs opens up new potential applications given the reduced constraints of the cryogenic package. In this paper, we explore the effects of Josephson junction and temperature variations through modeling a bi-SQUID system of equations for different designs based on step-edge Josephson junctions.
