The cathode pads are read-out by AFTER ASIC which diagram is presented Figure 9Figure 9. One chip has 72 active channels and 4 reference channels for pedestal subtraction. Each channel consists of charge-sensitive preamplifier, pole-zero cancellation of preamplifier decay time, RC2 shaper and 512-cell SCA to store waveform. Amplifier gain, pole-zero time constant and shaping time are programmable.
