Adoption of reversible logic circuits to achieve lower power and robust design is widely proved. The assumption of reversible logic to analog mixed circuit design is still naive. In this paper, a generic R2R Digital to Analog Converter (DAC) based on reversible logic design is proposed. Reversible logic circuitry for the DAC has been realized using Quasi-Floating Gate (QFG) technique and this helps in further reduction of power and improves the robustness of the converter.
