The above circuit may be used for (a) current adjustment, (b) current stabilization and (c) level offset. In the above figure, I(in) denotes the supply current. I(m) (O) denotes the threshold current of a Josephson device J1 in the absence of control bias current. I(m) (B) is the (suppressed) threshold current of device J1 in the presence of bias current. I(min) is assumed to be zero, and inductances L(1) and L(2) are inductances the first of which is in series with the device J1 and the other of which represents the inductance of the loop K shunting device J1. It is postulated that the adjusted, stablized and offset currents are used solely as control currents in superconducting loops.
