ABSTRACT:
A circuit including a sensing circuit, which includes a first delay circuit and a tuning circuit. The tuning circuit includes a sense counter and a reference counter. The sense counter is coupled to the first delay circuit and is configured to count a number of oscillations provided by the first delay circuit and provide a notification to the tuning circuit when the sense counter reaches a threshold value. The reference counter is coupled to the sense counter and a reference clock. The reference counter is configured to store a reference time which represents a time elapsed for the sense counter to reach the threshold value. Also included in the circuit is a second delay circuit coupled to the sensing circuit.
