Discriminator ASIC for the SPD VFE of the LHCb calorimeter

A monolithic prototype for the analogue readout of the Scintillator Pad Detector (SPD) of the LHCb Calorimeter is presented. A low power version that works at 3.3 V has been designed using the 0.8 um-BiCMOS technology of AMS. It consists on a charge discriminator with a dual path structure formed by...

description A monolithic prototype for the analogue readout of the Scintillator Pad Detector (SPD) of the LHCb Calorimeter is presented. A low power version that works at 3.3 V has been designed using the 0.8 um-BiCMOS technology of AMS. It consists on a charge discriminator with a dual path structure formed by an integrator, a track and hold, a subtractor and a comparator. Each circuit has 8 full channels. The chip also includes a DAC and serial digital control interface to program the threshold of the discriminator. Design, simulation and test results for the 8 channel prototype are presented.
