    Abstract

    We have constructed a two-stage SQUID amplifier intended for multiplexed cryogenic detector arrays. The upper SQUID is a locally linearized 6 × 80 array showing 0.13 μΦ0 Hz − 1/2 flux noise at 4.2 K. The lower linearized 4 × 3 SQUID array has decoupled input and feedback coils and shows 0.28  μΦ0 Hz − 1/2 flux noise at 4.2 K. Design principles and measured performance are reviewed.
