Abstract :
This paper presents a study on a digitally calibrated DAC, based on a strictly R-2R topology that is able to derive high resolution - high performance DACs, in terms of INL and DNL. It has been proven by simulations that the performance of the conventional R-2R DAC can be optimized, regardless of resistors tolerance and the DAC resolution.
