Basic Low Power techniques to reduce Power

In the process of finding all the advanced techniques to reduce power, we tend to ignore the basic techniques available with the majority of EDA tools. Some of these techniques that are available today and can reduce power to a great extent are :- (1) Clock gating (2) Sizing (3) Factoring (4) Pin swapping (5) […]

Finally I am back from very long business trip.During my trip, I got a chance to interact with many designers, who are about to start designing chips with MV/MTCMOS in mind. The most common concern everyone had before starting to implement the design are  (1) How much Leakage Power Can I save if I use MTCMOS design style? […]
