Abstract
An analog to digital converter with increased sub-range resolution. The device includes an analog front end that produces an analog communication signal, a digital front end that receives a digital communication signal, and an Analog to Digital Converter (ADC) that samples the analog communication signal across a full-range. The ADC includes a full-range ADC having a first quantization accuracy configured to sample the analog communication signal across the full-range and a central sub-range ADC having a second quantization accuracy greater than the first quantization accuracy and configured to sample the analog communication signal across a central sub-range of the full-range. The ADC also includes signal combining circuitry configured to process outputs of the full-range ADC and the central sub-range ADC to create the digital communication signal.
