Abstract
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.
