Abstract
An analog to digital converter with increased sub-range resolution and method for using the analog to digital converter is described herein. 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 plurality of sub-range ADCs, each sub-range ADC measuring the analog communication signal across at least one respective sub-range of the full-range, the plurality of sub-ranges extending across the full-range, a central sub-range ADC having greater quantization accuracy than at least one other sub-range ADC. The ADC also includes signal combining circuitry operable to process outputs of the plurality of sub-range ADCs to create the digital communication signal.
