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…
Study on Timing Performance of a Readout Circuit for SiPM
Liwei Wang, Yonggang Wang, Qiang Cao +2
In recent years, SiPM photoelectric devices have drawn much attention in the domain of time-of-flight-based positron emission tomography (TOF-PET). Using them to construct PET dete…
FPGA Based Pico-second Time Measurement System for a DIRC-like TOF Detector
Qiang Cao, Xin Li, Liwei Wang +3
A prototype of DIRC-like Time-of-Flight detector (DTOF), including a pico-second time measurement electronics, is developed and tested preliminarily. The basic structure of DTOF is…
Nuclear Pulse Charge Measurement with a Method of Time over Linear Threshold
Zhengqi Song, Yonggang Wang, Yong Xiao +1
Time over dynamic threshold (TODT) method, proposed in our previous work, has been successfully used for nuclear pulse charge measurement in PET detectors. It has advantages of str…
A 5.5 ps Time-interval RMS Precision Time-to-Digital Convertor Implemented in Intel Arria 10 FPGA
Jie Kuang, Yonggang Wang
As an important part of the field programmable gate array (FPGA) market, Intel FPGA has also great potential for implementation of time-to-digital convertor (TDC). In this paper, t…
