US Patent 8004043 - CNTFET logic

http://www.freepatentsonline.com/8004043.html

This patent from Intel appears to include some basic claims covering a carbon nanotube based logic system useful as building blocks for nanoscale reconstruction of inverter, NAND, and NOR logic gates. Claim 1 reads:

1. An integrated circuit, comprising:

first and second CNTFETs coupled in series between high and low supply references, the first CNTFET having a top gate to provide a logical input to receive High and Low logical values, the second CNTFET having a top gate coupled to a bias supply so that the second CNTFET provides an active load for the first CNTFET to provide suitable logical High and Low output levels.
