In this paper we present a 32-channel integrated circuit (ASIC) designed for a multi-anode silicon drift detector for X-ray imaging and spectroscopy (0.5 ÷ 100 keV). The ASIC includes 32 read-out front-end channels (ROC), each consisting of a low-noise preamplifier, a second-order RC-CR pulse shaper, a peak stretcher, an amplitude and a peak discriminator, as well as a reset and pile-up rejection...
A CMOS charge readout ASIC (SD7110) for flat-panel X-ray detectors was designed and tested. This ASIC contains 128 readout channels, with each channel consisting of a charge sensitive amplifier, a correlated double sampler, and a track-and-hold circuit. Channel outputs are read out via a 128:1 analog multiplexer and fed into an external 16-bit A/D converter. Conversion gain can be selected from 0...
