ABSTRACT:
A controller may include a measurement circuit configured to generate a proxy signal representing delay variations in the controller. The measurement circuit may also generate a measurement value from the proxy signal. A control circuit may be configured to convert the measurement value into a control value. A delay circuit may be adjusted by the control value to alter an amount of delay of a signal.
