Using reciprocity theorem to analyze R-2R network DACs

摘要: R-2R network [1-3] are widely used in DAC [4-7]. Shown figure 1 is a typical with resistors of R lying at the bridges and 2R on branches except for right end resistor R. From basic circuit law, we can see values resistance seen from nodes A, B, C, D E——including branch under these node——are all We call such feature to be equal-resistance feature.
