Abstract
Superconducting output amplifiers with interstage filters and related methods are described. An example superconducting output amplifier includes a first superconducting output amplifier stage and a second superconducting output amplifier stage. The superconducting output amplifier may further include a first terminal for receiving a first single flux quantum (SFQ) pulse train and coupling the SFQ pulse train to each of the first superconducting output amplifier stage and the second superconducting output amplifier stage. The superconducting output amplifier may further include an interstage filter comprising a damped Josephson junction (JJ) coupled between the first superconducting output amplifier stage and the second superconducting output amplifier stage, where the interstage filter is arranged to reduce distortion in an output voltage waveform generated by the superconducting output amplifier in response to at least the first SFQ pulse train.
