  • Patent number: 9954437
    Abstract: One charge pump includes at least one delay element, a number of inverters, and a flip flop coupled in series, with an output of one inverter coupled in a feedback loop to one of the delay elements. The charge pump monitors a first supply voltage level, and turns off an oscillator of the charge pump when the first supply voltage drops below a certain level. This is accomplished in one embodiment by monitoring a first supply voltage level supplied to a charge pump, and turning off an oscillator of the charge pump when the first supply voltage drops below a certain level.

  • Patent number: 9171599
    Abstract: Circuits, apparatuses, and methods are disclosed for oscillators. In one such example oscillator circuit, a plurality of delay stages are coupled in series. A variable delay circuit stage is coupled to the plurality of delay stages and is configured to delay a signal through the variable delay circuit stage by a variable delay. The variable delay increases responsive to a rising magnitude of a supply voltage provided to the variable delay circuit stage.
