Title
4-Channel Front-End Integrated Circuit For Readout of Large Area of SiPM under Liquid Argon
Abstract
This paper presents the structure and transistor-level design of CMOS front-end amplifier for the readout of large area SiPM at LAr temperature (87 K). The front-end circuit, a transimpedance amplifier and a summing amplifier, has been designed using a standard 110 nm CMOS technology, and the simulation results with the foundry PDK are included in this work. Each stage is implemented in a Folded Cascode Operational Transimpedance Amplifier (OTA) architecture with a power rail of +1.25 V and -1.25 V, a power consumption of 95 mW and an open-loop gain over 100 dB. The target sensor is a SiPM tile of 24 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> produced in the Darkside collaboration project, with 6 M of quenching resistance and 6 nF/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> capacitance. For a single photoelectron (250 fC), the front-end can achieve a signal-noise ratio above 12 and a jitter better than 45 ns.
