原始语种摘要: In this paper, a DC-coupling readout circuit is presented in order to readout the signal from CdZnTe detectors. A differential stage is added in CSA to compensate the leakage current introduced by the CdZnTe crystal. A compact shaper is designed to achieve low area with wide range of adjustable peaking time from 3 μ s to 10 μ s . The area of proposed circuit is about 130 μ m × 1100 μ m . The experimental results show that the ENC is 70 e + 14 e /pF and the gain is about 152 mV/fC at the peaking time of 4 μ s .
