Patent ID: 7746169

Claim:
A low noise amplifier (LNA) having a first differential input node and a second differential input node, the LNA comprising: a first transistor biased in the saturation region, wherein a gate of the first transistor is coupled to the first differential input node, wherein the first transistor generates a first distortion signal onto a drain of the first transistor; a second transistor biased in the saturation region, wherein a gate of the second transistor is coupled to the second differential input node, wherein the second transistor generates a second distortion signal onto a drain of the second transistor; a third transistor having a gate that is switchably selectively couplable to either a drain of the first transistor or to a drain of the second transistor; and a fourth transistor having a gate that is switchably selectively couplable to either the drain of the second transistor or to the drain of the first transistor.
