A widely tunable parametric amplifier based on a SQUID array resonator
, 2007 We create a Josephson parametric amplifier from a transmission line resonator whose inner conductor is made from a series SQUID array. By changing the magnetic flux through the SQUID loops, we are able to adjust the circuit's resonance frequency and ...
