Binary weighted D/A converters with mismatch-shaping

A D/A convertor suited to multibit sigma-delta modulators is described. This convertor is able to shape the spectrum of the error caused by the mismatch among its components. The hardware implementation is based on a simple, binary-weighted structure.
