PROCESS, VOLTAGE, AND TEMPERATURE INVARIANT TIME-TO-DIGITAL CONVERTER WITH SUB-GATE DELAY RESOLUTION

A control circuit and a method for delaying an electronic signal are provided, along with a time-to-digital converter including the control circuit. The example control circuit includes a first delay circuit having a first plurality of delay elements electrically connected in series and configured to generate a first control voltage associated with a first delay time. The control circuit further includes a second delay circuit having a second plurality of delay elements electrically connected at least in part in series. The second delay circuit is configured to generate a second control voltage associated with a second delay time. A first group of delay elements within the second plurality of delay elements exhibits the first delay time based on the first control voltage, and a second group of the second plurality of delay elements exhibits a second delay time based at least in part on the second control voltage.
