ABSTRACT:
A low noise amplifier includes an input stage. The input stage includes a first device configured to receive an input signal. A second device is connected to the first device. The second device has a predetermined input impedance. The input stage is configured so that a change in the input signal to the first device causes a linearly proportional change in a conductance of the first device. A voltage at a junction between the first device and the second device remains substantially constant due to the predetermined input impedance of the second device.
