Abstract

Researchers developed about a dozen semiconductor reversible (or adiabatic) logic chips since the early 1990s, validating circuit designs and proving the concept--but scale up required a further advance. This document shows that cryogenic inductors made of a new High Kinetic Inductance (HKI) material provide the advance. This material can be deposited as an integrated circuit layer, where it has enough energy recycling capacity to power a reversible circuit of the same size. This allows a designer to replicate and scale a complete reversible logic subsystem in accordance with Moore's law.
