Abstract
A front-end circuit composed of a high gain pulse amplifier cascaded by a threshold comparator has been designed for application in readout electronics of particle detectors. A prototype realized with a 8CH full custom chip in GaAs technology by GIGA foundry for application in gas chamber particle detector (RPC) is described. The chip exhibits a 0.2 mV minimum threshold, 150 MHz bandwidth and 50 mW per channel of power consumption.
