DAC9881high precisionA R2R ladder circuit implementation of a digital-to-analog convertor (DAC) may be configured to compensate for mismatch in each of a plurality of current sources in the R2R ladder circuit. The compensating of mismatch in each of the plurality of current sources may be ...
This technique, which allows creating electric links between diffusion regions, is used to correct mismatch errors in the R2R network of a 14 bit DAC. The converter's linearity, initially limited by mismatch level, is enhanced to reach 14 bit resolution. The circuit, fabricated in a standard ...
