Abstract

We suggest SQUID amplifier configuration intended for millikelvin refrigerators where cooling power is limited and hence high power efficiency is desirable. The configuration operates the SQUIDs in class-AB rather than the traditional class-A. A proof-of principle demonstration at T = 4.2 K is presented.
