Abstract
A circuit device includes a semiconductor device and an impedance matching network. The impedance matching network includes a superconductor material forming at least one inductor of the circuit device, and the superconductor material exhibits a kinetic inductance per unit square when in a superconducting state. The impedance matching network is configured to transform an impedance of the semiconductor device to match a predetermined second impedance during operation of the circuit device.
