  • Noise reduction in a voltage converter
    Patent number: 10305369
    Abstract: This application discusses techniques for reducing the energy of an output ripple in a voltage converter at a switching frequency of the voltage converter. In certain examples, an amplitude of a reference voltage can be modulated with a time-varying random value or pseudo-random value to provide a reduction in the energy of the output ripple at the switching frequency of the voltage converter.
    Type: Grant
