一种“死时间”少和自动校准容易的Wave Union TDC
A Automatic-calibration-easy Wave Union TDC wi th Less "Dead Ti me"
摘要
Abstract
Complex Wave Union encoder determined the "dead time"of time to digital converter (TDC) .To forme a new Wave Union C (WUC) ,it choosed the appropriate the delay unit number of transmitter ,changed A single launch of Wave Union A to continuous launch .Using Wallace tree and the structure of ROM ,WUC encoder used fewer resources ,had shorter time delay path .In Altera EP3C10E144C8 ,400 M HZ clock frequency ,80 delay chain ,it uses only the 166 logical unit and 2 .089 ns encod time .WUC real-time automatic calibration avoided bin-to-bin calibration of the all delay chain , and just only in launcher .On hardware ,real-time automatic calibration on hardware just needs a double delay chain length and a TDC clock that is not affected by environmental temperature and the voltage .关键词
