摘要： A Riordan-type gyrator circuit, consisting of two stages of differential operational amplifiers and five inductancedetermining impedances, is improved to avoid circuit latch-up at turn-on and to double the operative frequency range. The improvement involves deriving the input signal for the noninverting input terminal of the second stage from a voltage divider at the output of the first stage rather than from the same input signal applied to the non-inverting input terminal of the first stage. In addition to its gyrator function, the circuit can be modified to serve as an oscillator by employing positive feedback around the first stage. By rendering the voltage divider adjustable at the output of the first stage, the input conductance of the circuit is rendered variable between positive and negative conductances. The circuit also permits simulation of floating and mutually coupled inductors.

摘要： A supercurrent device comprising a pair of weak-link regions connected in a superconducting loop is driven by a current source. In series with the loop is an inductor for generating a magnetic field (i) proportional to the current flowing through the loop and (ii) the flux of which extends through the loop. The device, which exhibits both negative resistance and discrete supercurrent states at zero voltage, functions in several ways including: as a negative resistance oscillator, as a memory device, or as a highly sensitive linear magnetometer.
