High-Linearity Bi-SQUID: Design Map

We consider conditions allowing attending the highly linear voltage response of a bi-SQUID, taking into consideration the inductances of both loops and their shared inductance. The existence of the small latter one allows improving the law of the flux to phase transformation and essential enlarging margins of the high-linearity response. The reported data represent the design map for creation practical high-performance bi-SQUID-devices, taking into account a restricted fidelity in both design and fabrication.
