ABSTRACT:
A low noise amplifier (LNA) circuit includes a linear input stage including a first circuit that generates an output current and has a low input impedance. A device receives an input signal, communicates with the low impedance input of the first circuit, and includes a variable resistor having a resistance that varies based on the input signal.
