Fast binary readout front-end electronics for silicon strip detectors for low energy x-ray imaging applications

A binary readout architecture of multichannel front-end electronics used in a position-sensitive measurement system provides fully parallel signal processing, including data storage, and is the best one to cope with high intensity x-ray radiation. However, for low x-ray energy applications, the noise and matching performance of multichannel ASIC impose contradictory requirements on the high rate capability of the front-end electronics. These important aspects of ASIC design are analysed in this paper for two different generations of multichannel ASICs produced in CMOS technology and dedicated to low energy x-ray imaging applications using a silicon strip detector.
