摘      要：Integrated circuits of deep submicron(DSM) CMOS technology are advantageous in volume density, power consumption and thermal noise for multichannel particle detection systems,but there are challenges in the front-end circuit *** this paper,we present a 0.18μm CMOS front-end readout circuit for low noise CdZnTe detectors in tens of pF *** to the noise and gate leak problems in DSM technologies are discussed in detail.A prototype chip was designed,with a charge sensitive preamplifier,a 4th order semi-Gaussian shaper and several output *** results show that the chip has an equivalent noise charge of 164 e,without connecting it to a detector,with an integral nonlinearity of<0.21%and differential nonlinearity of<3.75%.
