A Preamplifier-discriminator circuit based on a Common Gate Feedforward TIA for fast time measurements using diamond detectors

This paper describes the design and simulation of a preamplifier-discriminator circuit based on a common-gate feedforward TIA architecture and a Leading Edge Discriminator for fast time measurements. The goal is to validate the use of such circuits with the new generation of radiation detectors based on diamond. The circuit has been designed in a 130 nm 1P8M CMOS technology and it is intended to be used as Front-End-Electronics (FEE) for the measure of the time of flight (TOF) using diamond detectors in order to realize a beam tagging hodoscope.
