In this paper, we develop a micro radiation probe with a CdZnTe detector. To obtain a high signal-to-noise ratio(SNR) performance, circuit simulation and analysis were performed before circuit design, to evaluate the signal characters and frequency response of the electronic design. We adopted a method to evaluate the electronic noise level of specific readout circuits design and determined a better timing parameter of the shaping circuit. Our results confirmed that using a proper design of charge sensitive amplifier(CSA) circuit and the filter system on the readout circuit improved the energy resolution of the probe. Energy spectrum measurement using a 137Cs source showed that the energy resolution of 662 keV γ-ray can reach 2.6%. This enables this microprobe for multi-nuclides recognition or nuclides to monitor in nuclear medicine applications.
