Abstract
A low noise amplifier (LNA) comprises an input stage to amplify an input signal, the input stage having a transconductance that has reduced gain variations in response to changes in process and environmental conditions. The input stage includes a first transistor. A second transistor communicates with the first transistor. A bias circuit biases the first transistor in a triode region and the second transistor in a saturation region, wherein an input of the LNA communicates with a control terminal of the first transistor.
