Abstract

A new hybrid CMOS-nanoscale circuit style has been developed that uses only one type of Field Effect Transistor (FET) in the logic portions of a design. This is enabled by CMOS providing control signals that coordinate the operation of the logic implemented in the nanoscale. In this paper, the new circuit style is explored, examples from a microprocessor design are shown, performance, manufacturing and density implications discussed. The system is based on the existing CMOS-nano hybrid fabric architecture NASIC, but the new circuit style reduces the requirements on devices and manufacturing from previous NASIC designs, significantly improves performance without any deterioration in circuit density.
