Abstract

We report on a simple, compact-size and cost-effective multi-channel charge-sensitive preamplifier system using the commercial IC operational amplifiers. An energy resolution of 5.6% at 511keV is achieved with a large size (10×10×1mm3) planar CdTe detector. The system is well suited for use with the compound semiconductor detectors in the applications in which the rather high power consumption of the system (320mW per channel) can be tolerated.
