Abstract

High-performance single flux quantum (SFQ) pulse amplifier (driver) based on superconducting quantum interference filter (SQIF) or near regular array of SQUIDs has been developed, fabricated, and tested. The driver part coupling method and circuit optimizations are discussed. The first test results of the driver prototype are reported. The experimental results confirm performance advantages of this driver design approach.
