1. A circuit comprises:
- a timer coupled to a controller; and
the controller configured to determine a calibration state of the circuit, to determine an active mode state of the circuit, to select a type of calibration operation based on the calibration state, and to control timing of the selected type of calibration operation in response to determining the calibration state to correspond to a time when the circuit is not active, the controller is configured to perform;
a first type of calibration when the timer exceeds a first threshold;
a second type of calibration when the timer exceeds a second threshold; and
a third type of calibration when the timer exceeds a third threshold.

Abstract
A circuit includes a controller configured to determine a calibration state of a circuit, to determine an active mode state of the circuit, and to select a type of calibration operation based on the calibration state. The controller is configured to control timing of the selected type of calibration operation in response to determining the calibration state to correspond to a time when the circuit is not active.
