Abstract

The design results of a charge-sensitive amplifier (CSA) with a pseudo-differential output are presented. The CSA is intended for operation with signals of both polarities at the dynamic range up to 100 fC and parasitic detector capacitances up to 100 pF. In order to form a pseudo-differential signal, a first-order low-pass filter having a cutoff frequency of several hertz was used. CSA is designed in 180 nm CMOS process.
