Architecture of the multi-tap-delay-line time-interval measurement module implemented in FPGA device
AbstractThis paper describes the architecture of a Multi-Tap-Delay-Line (MTDL) time-interval measurement module of high resolution implemented in a single FPGA device. The new architecture of the measurement module enables to collect sixteen time-stamps during a single measuring cycle. It means that the measured time-interval can be precisely interpolated from the collection of the sixteen time-stamps after each measuring cycle. Such architecture of the measurement module leads directly to an increased resolution, to a limited total measurement time and a decreased duty cycle of the measurement instrument.
