Delay Circuit with Multiple Dependencies

Abstract:

A delay circuit with multiple dependencies on various environmental parameters is disclosed. The delay circuit is configured to receive an input signal. The delay circuit includes a first circuit configured to generate a first amount of delay, wherein the first amount of delay has a direct relationship to a first environmental parameter. The delay circuit also includes a second circuit configured to generate a second amount of delay such that the second amount of delay has an inverse relationship to a second environmental parameter. The delay circuit is configured to generate a delayed output signal based on the first and second amounts of delay generated by the first and second circuits.
