Front-end electronics for the CMS preshower detector

The front-end readout system PACE2 for the CMS preshower detector consists of two chips: Delta is a 32 channel preamplifier 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 wi...

Sumario:The front-end readout system PACE2 for the CMS preshower detector consists of two chips: Delta is a 32 channel preamplifier 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 mu m BiCMOS DMILL radiation tolerant technology. The performance in terms of dynamic range, linearity, noise, peaking time and memory uniformity are presented.
