Design of low noise CMOS charge sensitive amplifier ASIC

The number of channel of front-end electronics has been increasing rapidly in recent applications of radiation detection, requiring more and more integrated circuit. How to implement nuclear electronics with high-density, low-cost and high performance and reliability has become a critical issue. Due to its low cost and capability for custom design, CMOS ASIC technology is being the working horse for monolithic nuclear electronics. The authors have designed low noise CMOS charge sensitive amplifiers for first run prototyping using CSMC 0.6 μm CMOS process. (authors)
