Extrapolating analog-to-digital converter

48th Midwest Symposium on Circuits and Systems, 2005., 2005
We propose a new type of oversampled analog-to-digital converter. It uses digital extrapolators to predict the analog signal before it is converted, and a coarse quantizer to convert the prediction error. Such converters are expected to have reduced complexity in their analog circuitry, thanks to the processing in the digital domain.
