- Front-end Specifications and Architecture Overview

Radiations detectors convert part of the energy lost by an incident particle into an

electrical signal, which is then processed by suitable electronic techniques. The first

component of the readout chain is often an integrated circuit optimized to serve

a specific purpose (Application Specific Integrated Circuit, ASIC). In many cases,

the front-end chip must perform different tasks (amplification, filtering, analog-to-

digital conversion, high speed data transmission), making necessary the integration of

complex analog and digital circuits on the same silicon substrate. The physics of the

process under study, the sensor characteristics and other additional constraints such

as the power consumption, the number of channels and the space to fit the system in

determine the choice of the front-end electronics parameters.
