Latest Patents
Huang Zhang Xu holds a patent titled "Applying charge pump to realize frequency jitter for switched mode power controller." This patent discloses a method and apparatus for adding jitter to an oscillator to reduce electromagnetic interference (EMI). The oscillator circuit includes an oscillator that generates a first clock with a first frequency and a frequency jitter circuit that utilizes a charge pump. This charge pump charges and discharges first and second capacitors repeatedly to obtain a time-varying voltage with a second frequency. The time-varying voltage is coupled to the oscillator, allowing the first frequency to vary within a specific range. The charge pump features a first switch for connecting the first capacitor to a voltage source and a second switch for coupling the first capacitor to the second capacitor. This configuration enables charge transfer between the capacitors to provide the time-varying voltage.
