Classification: CPC H  G | IPC H

Claim 9:
10. A kinetic inductance parametric amplifier for performing phase-sensitive amplification, the amplifier comprising:
an input port arranged to receive a pump tone, a DC bias and input signal;
an output port arranged to provide an amplified or de-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;
wherein the tunable stepped-impedance assembly is tuned at a frequency that allows for the amplifier to resonate at a predetermined frequency and wherein the pump tone has a frequency twice that of the input signal and wherein the DC biasing signal is transmitted to the high kinetic inductance line.
