Abstract: In examples, a system includes a differential input device having a first input and a second input. The system includes a window generator configured to output, at a first output, a first voltage above a reference voltage and a second voltage, at a second output, below the reference voltage. The system includes a multiplexer coupled to the first output and the second output, the multiplexer configured to receive the first voltage, the second voltage, and an input voltage. The system includes a selector coupled to the multiplexer and configured to select the first voltage, the second voltage, or the input voltage based on a value of the input voltage, where the selector is configured to cause the multiplexer to provide the selected voltage to the first input of the differential input device, where a voltage source provides the reference voltage to the second input of the differential input device.

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.
