Abstract
A gain controllable low noise amplifier (LNA) (,) with automatic linearity enhancement utilizes an amplifier stage (,) for amplifying a radio frequency (RF) input signal and a dynamically controllable feedback loop amplifier stage (,) for providing negative feedback to the feedback amplifier. A bias controller (,) is coupled to the dynamically controllable feedback loop amplifier stage (,) for monitoring a receiver automatic gain control (AGC) system (,) and providing a dynamic bias to the feedback loop amplifier stage (,) to improve linearity to the LNA in the presence of strong on-channel and off-channel signal conditions.
