Logic circuits with carbon nanotube transistors

An integrated circuit, comprising: First and second CNTFETs which are coupled between a high and a low supply reference in series, wherein the first CNTFET having a gate for providing a logical input for receiving high and low logic values, said second CNTFET a coupled with a voltage supply gate, whereby the second CNTFET to provide an active load for the first CNTFET to provide suitable logic high and low output levels.
