Current mode charge pulse amplifier in CMOS technology for use with particle detectors

Abstract

This amplifier is intended to be part of the front-end of a larger read-out chip to be used with particle detectors. The demands of read-out electronics are low power, low noise and high speed. At the input a charge pulse of 25000 electrons (4 fC) is applied to study the behaviour of the amplifier. The amplifier has a gain of ±12 mV/fC depending on the biasing condition, a peaking time of 35 ns and a power consumption of <500 µW.
