Pronciple of the New AdjustedArchitecture of R-2R D/A Converter
Polešáková, Zuzana
Original R-2R D/A Converter architecture has a shortcoming – while resolution is bigger than 7 bits, switching of MSBs causes a significant non-linearity error, which may even cause DAC to be non-monotonous. A possible solution to this issue is shown in this paper: dividing MSBs into subbits of a lower weight. Analog circuitry and digital driving is published in this paper.
