Abstract: In at least some embodiments, a system comprises a frequency generator configured to generate a second clock signal having a second frequency using a first clock signal having a first frequency. The second frequency is offset from the first frequency and each of a plurality of harmonic frequencies of the second frequency is offset from a harmonic frequency of the first frequency. The system also includes a power converter configured to produce a power signal that at least partially corresponds to the second frequency. The system further comprises an analog-to-digital converter (ADC) configured to sample and convert analog voltages at the first frequency. The ADC is powered by the power signal.
