ALEXANDRIA, Va., Aug. 28 -- Pike Group, Dover, Del., has been assigned a patent (8,522,184) developed by Lester F. Ludwig, Belmont, Calif., for a "hierachically-modular nanoelectronic differential amplifiers, op amps, and associated current sources utilizing carbon nanotubes, graphene nanoribbons, printed electronics, polymer semiconductors, or other related materials."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A method for implementing electronic circuit modules on elongated structures of semiconducting materials such as carbon nanotubes, graphene nanoribbons, elongated structures of semiconducting polymers or organic semiconductors, other related materials, and printed electronics strip structures is disclosed. The method provides that a plurality of modules can be implemented on distinct adjacent portions of the same elongated structure of semiconducting materials. In powering the modules, each circuit comprises a chain of electronic components arranged so that each end of the chain can function as a power supply terminal. Larger electronic circuit modules can be created from smaller module, and such a modular hierarchy may be extended to an arbitrary number of levels. In a Computer Aided Design (CAD) applications for nanoelectronics and printed electronics, designs for hierarchies electronic circuit modules can be stored and retrieved from one or more a libraries of circuit designs."
The patent application was filed on May 24, 2011 (13/114,833). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=8,522,184.PN.&OS=PN/8,522,184&RS=PN/8,522,184
