Abstract :
The authors present the design and characterization of an eight-channel preamplifier-shaper intended for use with silicon strip detectors ranging in capacitance from 1 to 20 pF. The nominal peaking time of the circuit is 200 ns with an adjustment range of ±50 ns. The circuit has a pitch (width) of 85 μm/channel with a power dissipation of 1.2 mW/channel, and has been fabricated in 2 μm p-well CMOS. The 0 pF noise is 330 e with a noise slope of 64 e/pF. The design approach is presented as well as both test bench and strip detector measurements
