This work presents FAST, a multichannel readout ASIC designed to measure the time of arrival of MIP particles in Ultra-Fast Silicon Detectors (UFSD) with a time resolution of about 30 ps. The FAST ASIC is oriented to future High Energy Physics experiments, where high time resolution is exploited to mitigate pile-up effects, and more generally, to those applications that require accurate Time-of-Flight Silicon systems with low power consumption. The prototype has been designed in 110 nm CMOS technology, in three different flavors of front-end architecture. Each flavor is implemented in a different 20-channel ASIC. For all flavors, the power consumption of the front-end is 1.2 mW/channel. The three flavors of FAST are described in the paper, together with the simulation showing the timing performance of FAST coupled to different sensors geometries.

Abstract
This work presents FAST, a multichannel readout ASIC designed to measure the time of arrival of MIP particles in Ultra-Fast Silicon Detectors (UFSD) with a time resolution of about 30 ps. The FAST ASIC is oriented to future High Energy Physics experiments, where high time resolution is exploited to mitigate pile-up effects, and more generally, to those applications that require accurate Time-of-Flight Silicon systems with low power consumption. The prototype has been designed in 110 nm CMOS technology, in three different flavors of front-end architecture. Each flavor is implemented in a different 20-channel ASIC. For all flavors, the power consumption of the front-end is 1.2 mW/channel. The three flavors of FAST are described in the paper, together with the simulation showing the timing performance of FAST coupled to different sensors geometries.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
