Abstract :
In this contribution we present a readout electronics for a liquid-argon calorimeter. It has been designed and optimized for operation at cryogenic temperatures and it is integrated in an n-well 2¿m CMOS technology. The chip contains 16 analog channels with switched-capacitors circuits for charge collection, storage, and amplification, averaging and correlated double sampling circuits for noise reduction, trigger signal generator, analog multiplexer, digital control for analog switching and 50 ¿ cable drivers.
