Abstract :
A novel time-to-digital converter (TDC) architecture, based on a two-dimensional time-delay matrix is presented. This architecture offers the advantage, over using a regular linear time-delay chain, of minimal pulse-pair resolution and dead time. The architecture was implemented on a XCV300 Virtex FPGA from Xilinx. The resulting TDC allows time measurements over a 21-ms interval with 150 ps resolution, and 2.5 ns maximum pulse-pair resolution and dead time.
