Abstract :
Exact formulas for the effect of series and Shunt feedback on noise figure are derived. The resulting noise figure is expressed by the feedback impedance, the two-port parameters, and the noise parameters of the device without feedback. The formulas are useful when considering the effect of biasing network and package elements on noise figure.
