Design and performance of a CMOS charge sensitive amplifier - cable driver combination is being described. The single stage differential input amplifier has an open loop gain of 78 dB and a corner frequency of 7 kHz at 7.5 mW power dissipation. Power consumption of the amplifier can be steered by an external bias source. Using the bias input for fast turn on/off gives a settling time of 1 micrometers. The 1/f noise charge contribution amounts to 400+11C sub pf electrons, independent of power consumption. (IMS)
