Progress on the digital-to-time converter research

Our research paper High precision low jitter pulse generator implemented with FPGA transceiver has been published on the journal of Measurement. The link is 10.1016/j.measurement.2024.114657.

In this paper, a new method for DTC design based on the FPGA transceiver is proposed and demonstrated. High precision about 1 picosecond is achieved. The jitter is obviously much lower compared to other FPGA based design.
