Design of A Readout Circuit for Nuclear Radiation Detector
Abstract：Natural resources consumption dramatically makes human pay more and more attention to some high energy material utilization, such as, nuclear materials. Laid the foundation for the development of nuclear technology is widely used in nuclear material. With the development of nuclear technology, the scope of application of nuclear materials is also expanding. However, the application of nuclear material benefits but also brings the nuclear radiation fear for human. Radiation of high energy nuclear will produce great harm to the human body, in order to avoid this situation, it is necessary to detect nuclear radiation. Detection of nuclear radiation is related to stability of popular feelings and personal safety, and it is of great significance. In view of the weak charge signal CZT nuclear radiation detector pixel array detector, TSMC 0.35 process based on CMOS, the analog readout circuit design, laid the foundation for the single chip CZT nuclear radiation pixel array detector integrated.
