Abstract
An apparatus increases the dynamic range of a time to digital converter. The apparatus includes: an input network configured to receive a first signal, a second signal, and a control signal having a sign value; and a time-to-digital converter (TDC) configured to generate a digital code value that represents a time delay value between the first signal and the second signal. The input network is configured to switch where the first signal and second signal are output in response to the sign value that is determined by the time delay value between the first signal and the second signal.
