摘要： Predictive Analog-to-Digital Converter system in one embodiment includes a sampling section producing a sampled analog input signal with a first summer section combining the sampled analog input signal and an analog prediction signal to produce an analog prediction error signal. There is at least one error analog-to-digital convertor digitizing the analog prediction error signal, wherein a digital error signal output from the error analog-to-digital convertor is one of a full bitwidth error signal during an over-range condition else a lower bitwidth error signal. A second summer is coupled to the digital error signal output and a digital prediction signal, and generates a full bitwidth digital output signal. A feedback section is coupled to the digital output signal and providing the digital prediction signal and the analog prediction signal.
