The Current-Steering DAC
to this code-dependent output resis-tance, the input–output charac-teristic exhibits compression as D in increases [Figure 7(d)]. It can be shown that the maximum INL aris-ing from this effect is given by IR u LMr/(4 O), 2 which, normalized to the full-scale output voltage, is ap-proximately equal to MR LO/(4r ). For example, if M =1024 and R ...
