Abstract:
A subranging time-to-digital converter (TDC) is disclosed that includes two ring oscillators for determining a time difference between two clock edges.

Claim (Index 17):
A digital phase-locked loop, comprising;\n an accumulator for determining a reference phase from a reference clock signal; a loop filter configured to filter a phase error between the reference phase and a variable phase to produce a control word; a digitally-controlled oscillator for oscillating a clock output signal responsive to the control word; and a time-to-digital converter configured to measure a delay between a first clock edge for the clock output signal and a second clock edge for the reference clock signal to produce the variable phase, wherein the time-to-digital converter includes a first ring oscillator configured to oscillate a first oscillator output signal responsive to the first clock edge and a second ring oscillator configured to oscillate a second oscillator output signal responsive to the second clock edge, and wherein the time-to-digital converter is configured to measure the delay responsive to the cycles of the first oscillator output signal and to cycles of the second oscillator output signal.
