  A 64-channel mixed-mode ASIC, suitable for particle detectors of large
dynamic range and high capacitance up to hundreds of pF, is presented here.
Each channel features an analogue front-end for signal amplification and
filtering, and a mixed signal back-end to digitise and store the signal
information. The analogue part consists of a low input-impedance programmable
gain pre-amplifier based on a regulated common-gate (RCG) input stage, two
shapers optimised for time and energy measurements. The back-end part mainly
includes discriminators, TDCs and ADCs, which are used to process the signal
and encode both the time of arrival and the charge in the input signal with a
fully digital output. The programmable gain of the front-end (up to 400 fC
input dynamic range) and the versatile back-end allow the readout of different
gaseous detectors like GEM, MicroMEGAS and MWPC. The ASIC is designed for an
event rate up to 100 kHz per channel and a power consumption less than 9
mW/channel, has been fabricated in a 110 nm CMOS technology.
