A KINETIC INDUCTANCE PARAMETRIC AMPLIFIER

摘要

The present disclosure relates to a kinetic inductance parametric amplifier that comprises an input port arranged to receive a pump tone, a DC bias and input signal; an output port arranged to provide an amplified version of the input signal; a tunable stepped-impedance assembly arranged to attenuate and/or filter predetermined frequency bands; and a high kinetic inductance line. The tunable stepped-impedance assembly is tuned at a frequency that allows for the amplifier to resonate at a predetermined frequency and a pump tone with a frequency higher than the input signal and a DC biasing signal to be transmitted to the high kinetic inductance line.
