A resolution-enhancing analog-to-digital signal conversion circuit is provided. The circuit includes a plurality of analog-to-digital converters arranged in parallel. Each analog-to-digital converter of the plurality of analog-to-digital converters is configured to output a digital signal that identifies an analog signal input to that analog-to-digital converter. The circuit further includes an input regulation module configured to clip the analog signal input to any of the plurality of analog-to-digital converters to within the voltage range corresponding to that analog-to-digital converter if such an analog signal otherwise is outside of the voltage range. The circuit further includes a controller configured to receive the digital signal output from each analog-to-digital converter and output an encoded signal based on one or more such digital signal that is received from an unclipped analog-to-digital converter having a highest analog-to-digital conversion resolution.
