Abstract
The application discloses a time-to-digital conversion circuit () including a first oscillator (), a second oscillator (), a first counting circuit (), a second counting circuit (), a first conversion circuit () and a processing circuit (). The first oscillator is activated by a first signal and includes oscillating units having a first delay amount, wherein the first counting circuit is configured to count a number of times that the first tail end output signal of the first oscillator changes and store the same as a first counting result; the second counting circuit counts a number of oscillating units with an output change, other than the first tail end oscillating unit and stores the same as a second counting result; the first conversion circuit generates a first conversion signal according to the first counting result and the second counting result; the processing circuit generates the output signal at least according to the first conversion signal.
