“…Given that we are working to develop a timing measurement system with picosecond resolution, even the minute variations in the physical distances between any two-carry logic (CARRY4) blocks in the WU-A architecture will lead to high non-linearity. Therefore, a bin-by-bin calibration is necessary [ 40 ]. This part of the calibration using data processing is performed with an automatic calibration method.…”

“…Output signal Input signal Delay parameter The focus of the delay generator designed in this article is a time method (structure) called a carry delay chain [10][11][12], which is mainly used in various delay systems and time interval measurement systems, and it is currently used more frequently as a time method. In the field of time interval measurement, this time method is also called delay line interpolation [13][14][15]. The carry delay chain is mainly implemented in a FPGA or an ASIC, which have high degrees of integration.…”
