Abstract
Exact formulas for the noise parameters and noise figure of amplifiers with parallel feedback and lossy input and output matching circuits are derived. The formulas which take into account the thermal agitation of all circuit elements are applicable to feedback and lossy match amplifiers, as well as amplifiers that employ both principles simultaneously.Keywords
