  • METHODS AND APPARATUS TO COMPARE VOLTAGES
    Publication number: 20240118322
    Abstract: An example device includes an analog comparator circuitry having a first input configured to couple to an input voltage and a second input configured to couple to a reference voltage, the analog comparator circuitry configured to output a digital value corresponding to a difference between the input voltage and the reference voltage and output sampler circuitry configured to: produce a plurality of samples of the difference, and count the number of samples in which the input voltage is greater than the reference voltage. The example device also includes reference adaption circuitry configured to: determine, based on the count, whether to adjust the reference voltage; responsive to a determination to adjust the reference voltage, determine, based on the count, an amount of adjustment; and responsive to a determination not to adjust the reference voltage, provide an indication of the reference voltage to processor circuitry.
    Type: Application
