Abstract
An amplifier comprising a Low Noise Amplifier (LNA) to amplify a Radio Frequency (RF) signal. The LNA having a transconductance and including an input stage to receive the RF signal. The LNA again varying as a function of changes in conditions. A bias assembly to generate a bias current to bias the LNA input stage. The bias assembly configured to reduce variation of the LNA gain to changes in conditions.
