  • Applying charge pump to realize frequency jitter for switched mode power controller
    Patent number: 8093955
    Abstract: Method and apparatus for adding jitter to an oscillator for reducing EMI are disclosed An oscillator circuit includes an oscillator configured to generate a first clock having a first frequency and a frequency jitter circuit including a charge pump configured to charge and discharge first and second capacitors repeatedly for obtaining a time-varying voltage having a second frequency. The time-varying voltage is coupled to the oscillator to vary the first frequency within a frequency range. The charge pump includes a first switch for coupling the first capacitor to a voltage source and a second switch for coupling the first capacitor to the second capacitor. A charge transfer between the first and second capacitors is configured to provide the time-varying voltage.
