Abstract
In accordance with an embodiment, a circuit includes a first oscillator having an oscillation frequency dependent on an input signal at a first input, where the first oscillator is configured to oscillate when an enable input is in a first state and freeze its phase or reduce its frequency when the enable input is in a second state. The circuit also includes a first time-to-digital converter having an input coupled to an output of the first oscillator, and a pulse generator having an input coupled to a first clock input of the circuit and an output coupled to the enable input of the first oscillator, where the pulse generator is configured to produce a pulse having pulse width less than a period of a clock signal at the first clock input.
