Abstract
An Analog-to-Digital Converter (ADC) device includes an input interface and conversion circuitry. The input interface is configured to receive an analog input signal. The conversion circuitry is configured to convert the analog input signal into a digital word by performing a sequence of iterations to determine respective bits of the digital word, wherein the sequence (i) progresses in descending order of bit significance of the bits, from a Most Significant Bit (MSB) to a Least Significant Bit (LSB), and (ii) repeats evaluation of a predefined number of Least-Significant Bits (LSBs) of the digital word multiple times, and determining a final value of the digital word by averaging the repeatedly-evaluated LSBs.
