A CMOS front-end ASIC for semiconductor radiation detectors is proposed.The ASIC comprises a charge sensitive amplifier,a gm-C type shaper,a peak detect and hold circuit,and two discriminators.The PDH and the discriminators,together with some logic circuits,provide the capability to reject trailing edge pile-up.The circuit has been designed in a 0.5?
