ALEXANDRIA, Va., Oct. 10 -- Arya Behzad of Poway, Calif., and C. Paul Lee of San Diego, have developed a method for gain control network.
According to the abstract released by the U.S. Patent & Trademark Office: "An apparatus and method to use a gain control network across source terminals of cascode transistors that drive a differential current to control gain. The drains of the cascode transistors are coupled to a load such as a mixer. The cascode arrangement provides high impedance coupling to the load and the proximity of the gain control network allows offsets to be gain tracked to signal gain."
The inventors were issued U.S. Patent No. 7,433,662 on Oct. 7.
The patent has been ...
