Novel fully integrated OTA based front-end analog processor for X-rays silicon strip detectors

Abstract

A space application fully integrated preamplifier - shaper system for X-rays silicon strip detectors is developed. An operational transconductance amplifier (OTA) based shaper architecture with continuous variable peaking time and programmable gain is designed using advanced filter design techniques. Considerations about the noise performance, the bandwidth and the output signal processing flexibility are also presented. The system was designed in 0.6 mum AMS process. Analysis is supported by simulation results, which confirm the exceptional system performance
