Abstract
A voltage regulator includes a delay chain having a plurality of delay elements, a thermometer to binary encoder coupled to multiple nodes in the delay chain to provide a first binary number that is indicative of an estimated delay of the delay chain, and a latch coupled to the thermometer to binary encoder to receive the binary number. The voltage regulator also includes a signal processing circuit for providing a control signal indicative of a difference between the first binary number with a second binary number that represents a target delay, and a voltage control circuit coupled to the signal processing circuit for providing an output voltage based on the control signal from the processing circuit.
