CPC H03F 19/00 (2013.01) | 18 Claims |
1. A kinetic inductance parametric 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 version of the input signal;
a tunable stepped-impedance assembly comprising a bandstop filter 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 kinetic inductance parametric amplifier to resonate at a predetermined frequency and wherein the pump tone has a frequency higher than the frequency of the input signal and the DC bias signal is transmitted to the high kinetic inductance line.
