An RC equivalent delay circuit includes an input node, an output node, a feedback node, and an intermediate node; a first inverter having an input coupled to the input node and an output coupled to the intermediate node; a second inverter having an input coupled to the intermediate node and an output coupled to the feedback node; a third inverter having an input coupled to the feedback node and an output coupled to the output node; and one or two switches having a first input coupled to the input node, a second input coupled to the feedback node, and an output coupled to the intermediate node.
