ALEXANDRIA, Va., Oct. 15 -- Kirk B. Ashby and Oliver I. Werther, both of McKinney, Texas, have developed a signal processing method.
According to the abstract released by the U.S. Patent & Trademark Office: "Disclosed are systems and methods which provide very linear amplification of signals using a linearized transconductance circuit. A transconductance amplifier configuration is shown which provides highly linearized operation utilizing a Darlington pair feedback circuit. Also shown are gain control configurations in which current steering circuitry is adapted to operate in its most linear region."
The inventors were issued U.S. Patent No. 7,436,262 on Oct. 14.
The patent has been ...
