Abstract :
During recent years, many readout integrated circuits for CZT radiation detectors have been studied particularly for use on pixilated detectors in imaging applications. The main challenge is to keep noise performance similar to discrete preamplifiers, even with lower power. This paper presents the design and the experimental evaluation of CMOS integrated charge sensitive preamplifiers intended for CZT radiation detectors. A comparison is made with discrete preamplifiers.
