Abstract
A method for low noise signal amplification includes modifying a signal by way of a first amplification stage and conveying the modified signal to a second amplification stage. The method continues with comparing an output of the second amplification stage with a signal ground in a low-frequency feedback loop and changing a bias voltage for the first amplification stage as a result of the comparing step.
