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…
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…
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…
Practical gigahertz quantum key distribution robust against channel disturbance
Shuang Wang, Wei Chen, Zhen-Qiang Yin +12
Quantum key distribution (QKD) provides an attractive solution for secure communication. However, channel disturbance severely limits its application when a QKD system is transfere…
