Abstract :
An IC readout front end system for space applications X-rays silicon strip detectors is presented. The system semi-Gaussian shaper is based on CMOS operational transconductance amplifiers (OTA) and is implemented using advanced design techniques. This innovative architecture provides a broad range of continuously variable peaking time, adjustable undershoot and programmable gain. The noise performance, the bandwidth and the output signal undershoot are also analytically examined. The system was designed in 0.6mum process by Austria Mikro Systeme. Simulation results using HSPICE (BSIM3V3.2 model) support the theoretical analysis and confirm the system capability to be used in a variety of readout applications
