Circuit Design Style for Energy Efficiency: LSDL and Compound Domino

Introduction of sub-90nm technology has made a profound impact on circuit designs. Thus, it requires understanding of existing design styles for desired energy-efficiency. The authors compare adder designs in the energy-delay space, implemented with Limited Switch Dynamic Logic (LSDL) and Compound Domino logic (CD) in a 65nm SOI (Silicon On Insulator) technology. Evaluation results show that LSDL can provide more than 35% energy savings than CD with 25% switching activity at relaxed cycle times greater than 10.5 FO4.
