A hybrid coarse-fine time-to-digital converter is disclosed. The hybrid coarse-fine time-to-digital converter is configured to receive a first input signal and a second input signal and to generate a digital output that corresponds to the time difference of between a rising edge of the first input signal and a rising edge of the second input signal. The hybrid coarse-fine time-to-digital converter comprises a coarse time-to-digital converter, a fine time-to-digital converter, and a correlated output generator.
