The analog front end for FastRICH: an ASIC for the LHCb RICH detector upgrade

# metadata.dc.description.abstract[].value
This work presents the analog circuitry of the FastRICH ASIC, a 16-channel ASIC, developed in a 65 nm CMOS technology specifically designed for the RICH detector at LHCb to readout detectors like Photomultiplier Tubes to be used at the LHC Run 4 and Silicon Photomultipliers candidates for Run 5. The front-end (FE) stage has an input impedance below 50 Ω and an input dynamic range from 5 μA to 5 mA with a power consumption of ∼5 mW/channel. The chip includes a Leading Edge Comparator (LED) and a Constant Fraction Discriminator (CFD) for time pick-off and a Time-to-Digital Converter (TDC) for digitization.
