Abstract :
An R2R DAC using three digital input levels rather than two is proposed as well as a modified two-level structure that emulates the three-level DAC´s benefits. This three-level structure provides power reductions of 79% and linearity improvements due to matching of a factor of 2 over the two-level case. Ideal implementation is also described in terms of the logic needed to code the DAC and the requirements of the additional third reference level.
