Review of FPGA-Based Digital-to-Time Converters

In the past few years, FPGA technology has rapidly improved, and the performance gap between FPGAs and ASICs is getting smaller and smaller. FPGA-based platforms are known for their high performance, low development cost, and pervasiveness. Researchers are enthusiastic about FPGA-based digital-to-time converter (DTC) development. To determine the focus of future research efforts, it is crucial to analyze the evolution of FPGA-based DTC work. This study aims to present and discuss the existing DTC architectures and compare the advantages and disadvantages between them. A literature review of the state-of-the-art FPGA-based DTC is presented, highlighting its features, limitations, and application areas.
