We have designed and realised a Front-End chip for MPPC in standard CMOS 0.35$\mu$m technology. The channel presents a low input impedance in order to reduce as much as possible the recovery time of the sensor. This is achieved using the current domain for processing signals through the current conveyors (CCII) as building blocks of the channel. A current feed-back with low-pass filter has...
