Abstract
Examples are provided for converting an analog signal to a digital output signal using serial-ripple analog-to-digital conversion (ADC). An ADC circuit may include conversion stages coupled in series. Each conversion stage may generate a bit for the digital output signal. A data latch may receive bits for the digital output signal from the conversion stages and to provide the digital output signal based on the bits. A conversion stage may include a comparator circuit and a multiplexer circuit. The comparator circuit may compare a sampled input signal with a reference signal and to generate the associated bit of the digital output signal based on a result of the comparison. The multiplexer circuit may provide an associated reference signal to a comparator circuit of a next conversion stage, where the next conversion stage is subsequent to the conversion stage.
