Abstract :
A 180 nm CMOS front-end readout circuit for CdZnTe particle detector with tens of pF capacitance is presented. It uses switched-reset system and 4th-order complex pole semi-Gaussian shaper. The input MOSFET is optimized with the consideration of the properties of deep submicron technologies and the limitation of power dissipation. And a swing reduction technique is used on the switch signal to improve the parasitic effects. The post-layout simulation result shows that the readout ASIC has about a 300e ENC at 20 pF detector capacitance and 10 mW power dissipation.
