US Patent 7329931 - Nanotube mechanical switch for differential receiver circuit


This patent from Nantero applies their carbon nanotube switching devices toward the creation of a differential pair receiver circuit. Claim 1 reads:

1. A receiver circuit, comprising:

a differential input having a first and second input link;

a differential output having a first and second output link;

first and second switching elements in electrical communication with the input links and the output links, each switching element having an input node, an output node, a nanotube channel element, and a control structure disposed in relation to the nanotube channel element to controllably form and unform an electrically conductive channel between said input node and said output node; and

first and second MOS transistors, each in electrical communication with a reference signal and with the output node of a corresponding one of the first and second switching elements.
