Abstract
A circuit includes a sensing circuit, a control circuit, and a programmable delay circuit. The sensing circuit generates delay compensation signals that change in response to variations in at least one of a process and a temperature of the circuit. The control circuit generates dynamic control signals in response to the delay compensation signals. The programmable delay circuit is configurable to delay a signal transmitted through an external terminal of the circuit by a delay that is selected by the dynamic control signals.
