ABSTRACT:
A low noise amplifier (LNA) comprises a bias circuit having an output. A first transistor includes a control input that communicates with the bias circuit, a first terminal that generates a LNA output current and a second terminal. A device communicates with the second terminal of the first transistor, includes a variable resistor, and has a resistance that is modulated in response to an input signal to the LNA.
