Abstract :
We report on design and preliminary measurements of integrated charge sensitive amplifier dedicated to work with asynchronous high rate input signals. In this paper, we discuss the trade-off between high rate operation of CSA and its noise, taking into account the negative effects of pile-up pulses in readout electronics. The key element in the presented fast CSA is a pole-zero cancellation circuit. The architecture of the PZC circuit implemented in 0.35 mum CMOS technology is discussed in detailed. The first tests of high rate operation of CSA with PZC circuit up to 2 MHz of input signals are reported
