Reversible logic plays a very important role in recent times as reducing power consumption in digital logic design. Reversible logic contains a feature of recovering bit loss from unique input-output ...

A 1-MHz clock drives IC 3, providing very fine timing resolution for 50- or 60-Hz power. At the ac power's zero crossing, optoisolator IC 4 clears ripple counter IC 3, synchronizing the ripple counter ...

At ISSCC 2008 in San Francisco, IMEC, the Belgian research and development centre for micro- and nanotechnologies, has demonstrated several innovative solutions: three different converter types with ...
