摘要：
A low-noise readout array is proposed for use with high capacitance detectors. The readout array is composed of a pre-amplifier/amplifier chain. The signal processing chain is designed for use with CdZnTe gamma ray detectors employed by NASA for radiation detection. This approach employs correlated double sampling and capacitive matching to increase the signal-to-noise ratio. The readout array is custom designed to fit into one detector pixel. The pre-amplifier/amplifier chain is designed and simulated in 0.13u CMOS8RF IBM technology. The readout array results show that the signal-to-noise ratio is significantly improved compared to previous work done in this field.
