Adiabatic cmos design

A method of fabricating a CMOS module, the method comprising providing a CMOS circuit on a substrate, connecting said CMOS circuit between a first reference line and a second reference line via respective transistors being provided in series with said first and second reference lines, and providing first capacitive means in parallel with said first transistor and second capacitive means in parallel with said second transistor, such that, in use, said first and second transistors operate as first and second respective current sources.

An integrated circuit comprising a plurality of CMOS circuits connected in series with each other, said CMOS circuits being connected between a first reference line and second reference line, a first transistor being provided between at least one of said CMOS circuits and said first reference line and a second transistor being provided between at least one of said CMOS circuits and said second reference line, wherein first capacitive means is provided in parallel with said first transistor and second capacitive means is provided in parallel with said second transistor such that, in use, said first and second transistors operate as respective current sources.
