Abstract
A system includes an NL bit digital to analog converter (DAC) ladder module having NL ladder resistors connected in parallel, NL series resistors connected in series between the NL ladder resistors, and a plurality of switches. NL is an integer greater than one. Adjacent pairs of the plurality of switches are connected in series with respective ones of the ladder resistors. On resistances of each of the plurality of switches are approximately equal. A switch control module provides a plurality of switch control signals to respective ones of the plurality of switches.
