摘要
In this paper,to design a new preamplifier for optimum performances with charged-particle or heavy-ion detectors,the CMOS FET is implemented as a feedback capacitor Cfp,so that the entire system should be built only with MOSFET. This work is a revolution design because to realize an ASIC for a preamplifier circuit,the capacitor will also be included. We succeed after a simulation to maintain a rise time less than 3 ns,the output resistance less than 94 ? and the linearity almost good.
