Optimization of the Dynamic Parameters of the Controlled Superconductor

The theory of the operation of the controlled superconductor as a linear amplifier is briefly described. The relationship between constants which describe the physical operation of the controlled superconductor and the small-signal parameters of the device are developed, and the optimization of the small-signal parameters in terms of the geometry of the device is discussed. The current gain expressions of linear amplifiers in two circuit connections are presented and the conditions necessary for the optimization of these gains are also derived.
