Abstract
This paper presents the design and comparative evaluation of four low energy CMOS adiabatic drivers; ib-drive using a dual-rail structure with complementary input and output; scal-driver using a single input stage based on a single transistor driving a pair of cross-coupled CMOS inverters; ob-driver using an output stage with two inverters driven by a pre-driver circuit consisting of two differential cascode voltage switch (DCVS) logic cells; ee-driver using an output stage with two bootstrap capacitors driven by a pre-driver circuit consisting of two differential cascode voltage switch (DCVS) logic cells. When implemented on a 0.13µm CMOS 1.0V technology, ib-driver performs better than the other adiabatic circuits, in terms of the energy-delay product by up to 68%.
