Front-End Electronics for the Cms Preshower Detector
Abstract
The Front-End readout system PACE2 for the CMS Preshower detector consists of two chips: Delta is a 32 channel pre-amplifier and shaper that provides low noise, charge to voltage readout for large capacitive silicon sensors over a large dynamic range (up to 400 MIPs); PACE-AM contains a 32-channel wide, 160-cell deep, analog memory with a 32 to 1 multiplexer for serial readout. These chips are designed in .8 μm BiCMOS DMILL radiation tolerant technology. The performance in terms of dynamic range, linearity, noise, peaking time and memory uniformity are presented.
