  • Voltage regulator
    Patent number: 9705393
    Abstract: A method of operating a voltage regulator including a source voltage rail and a plurality of output voltage rails, the method including: converting a source voltage on the source voltage rail to a respective output voltage on each output voltage rail; selecting an output voltage rail; comparing the output voltage on the selected output voltage rail to a reference voltage for the selected output voltage rail; and if the output voltage of the selected output voltage rail is less than the reference voltage for the selected output voltage rail, controlling the voltage regulator to increase the output voltage on the selected output voltage rail, wherein the frequency at which an output voltage rail is selected is dependent upon the rate at which the voltage regulator has previously increased the output voltage on that output voltage rail.

  • LOCAL OSCILLATOR FREQUENCY CALIBRATION
    Publication number: 20150185263
    Abstract: A frequency locked loop for generating a clock signal, comprising: a controllable oscillator configured to, in dependence on a control signal, generate an oscillator signal having an oscillator signal frequency; a frequency divider coupled to the controllable oscillator configured to reduce the oscillator signal frequency to form a divided oscillator signal frequency; and a frequency detector coupled to the frequency divider and configured to generate the control signal in dependence on a reference signal frequency; wherein the frequency divider comprises a first counter and a second counter, the first counter configured to be clocked by the oscillator signal and to produce a first counter output signal, and the second counter configured to be clocked by the first counter output signal.
