Abstract
A general digital-to-analog converter (DAC), which encompasses popularly known weighted-resistor and R-2R ladder DACs as the special cases, is introduced. The weighted-resistor subfamily has been studied in the recent past. This paper presents a detailed study of the sub-family of ladder DACs. Some DACs have very interesting features. It is found that the R-2R ladder DAC not only has the least possible spread but also has the minimum total resistance. Also, there is another DAC which has the same spread of 2 as the R-2R ladder DAC but requires the minimum number of resistors
