A recently granted patent (Publication Number: US11923856B2) discloses a device incorporating a time-to-digital converter (TDC) with a unique configuration. The TDC includes multiple delay lines with varying delay times, arbiters, and logic components to accurately measure time differences between input signals. The device utilizes complementary metal-oxide-semiconductor (CMOS) buffers and delay flip-flops to achieve precise time-to-digital conversion. Additionally, the TDC is part of a time-based analog-to-digital converter (ADC) system, enhancing its functionality and versatility in various applications.

Furthermore, the patent describes a method for time-to-digital conversion using the TDC, involving delaying input signals, comparing delayed versions, and outputting digital signals based on the time differences. The method includes utilizing multiple sets of arbiters and delay elements to ensure accurate measurements and efficient processing. By incorporating various delay times and comparison techniques, the method enables high-resolution time measurements essential for applications requiring precise timing information. Overall, the patented TDC and associated method offer a sophisticated solution for time-to-digital conversion, catering to the growing demand for advanced time measurement technologies in diverse industries.
