Abstract :
A readout electronics for a liquid-argon calorimeter is discussed. It is designed and optimized for operation at cryogenic temperatures and it is integrated in an n-well 2-μm CMOS technology. The chip contains 16 analog channels with switched-capacitor circuits for charge collection, storage, and amplification, and averaging and correlated double-sampling circuits for noise reduction. Further components include a trigger generator, an analog multiplexer, digital control circuits for analog switching, and 50 ohm cable drivers
