Abstract

This paper presents an ultra low noise instrumentation based on cryogenic electronic integrated circuit. We have designed an ASIC (Application Specific Integrated Circuit) in standard BiCMOS SiGe 0.35 μm AMS technology. The main functions of this circuit, the readout and the control of a 24 to 1 SQUID multiplexer, is presented. We also report the cryogenic operation of each part of this ASIC.
