Method and apparatus for an LNA with high linearity and improved gain control
摘要:
A low noise amplifier (LNA) comprises an amplifier having an inverting input, a non-inverting input and an output. A first transistor has a control input that communicates with said output of said amplifier, a first terminal that generates a LNA output current and a second terminal that communicates with said inverting input. A device communicates with said second terminal of said first transistor, includes an output and has a resistance that is modulated in response to an input voltage to said LNA. The device is a variable resistor.
