An FPGA Based Fast Linear Discharge Method for Nuclear Pulse Digitization
Xiaoguang Kong, Yonggang Wang, Liwei Wang +2
Inspired by Wilkinson ADC method, we implement a fast linear discharge method based on FPGA to digitize nuclear pulse signal. In this scheme, we use a constant current source to di…
