Digital-to-Analog Converter Implementing Hybrid Conversion Architecture

A digital-to-analog converter (DAC) implements a hybrid conversion architecture where the input digital data is oversampled and a flash converter is used to convert the M most significant bits (MSBs) of the oversampled data while a sigma-delta (Sigma-Delta) converter is used to convert the remaining...

Zusammenfassung:A digital-to-analog converter (DAC) implements a hybrid conversion architecture where the input digital data is oversampled and a flash converter is used to convert the M most significant bits (MSBs) of the oversampled data while a sigma-delta (Sigma-Delta) converter is used to convert the remaining least significant bits (LSBs) of the oversampled data. In one embodiment, a merged flash converter is used to convert the M MSBs and the digital bit stream generated by the sigma-delta converter.
