1. An apparatus, comprising:
a first voltage regulator coupled to a first oscillator circuit;
a second voltage regulator coupled a second oscillator circuit or a delay circuit; and
a detector circuit coupled to the first oscillator circuit and the second oscillator circuit or the delay circuit, wherein the detector circuit is configured to:
detect characteristics of signaling received from the first oscillator circuit;
detect characteristics of signaling from the second oscillator circuit or the delay circuit; and
compare the detected characteristics of the signaling from the first oscillator circuit and the detected characteristics of the signaling from the second oscillator circuit or the delay circuit to determine whether the detected characteristics from the first oscillator circuit and the detected characteristics from the second oscillator circuit or the delay circuit meet a particular criterion for providing voltage manipulation to one or more components of the apparatus.
