The AC oscillator voltage amplitude may be increased for an increase in power through the high voltage rated isolation capacitors, and a larger value capacitor in the second voltage domain may provide for peak current demand from circuits in the second voltage domain.

  • Patent number: 8823447
    Abstract: Systems, methods, and computer readable media that can mitigate the effects of semiconductor aging in a semiconductor device are described. Traditional methods of mitigating semiconductor aging can be wasteful since they overcorrect for aging using a high operational voltage. The approach discussed herein steps up the operational voltage for the electronic device with time based on predetermined aging models. This allows power consumption by the electronic device, particularly early in the designed operational life, to be much less than it would otherwise be.

  • Patent number: 8754703
    Abstract: TASK: to provide an internal voltage trimming circuit having a simple configuration and operated by a consumption current smaller than that using a comparator. MEANS FOR SOLVING THE PROBLEM: An internal voltage trimming circuit comprises a trimming controller using a change in a counting value of a clock according to a current flowing through a transistor of a power supply current source for a clock generator to trim an internal voltage generated by an internal voltage generator. The trimming controller counts a first counting value of the clock when a predetermined reference voltage is applied to a control terminal of the transistor and a second counting value of the clock when the internal voltage is applied to the control terminal of the transistor and controls the internal voltage generated by the internal voltage generator to substantially coincide the second counting value with the first counting value.
