Abstract
Exact and simple expressions have been obtained for the intrinsic noise figure of monolithic microwave integrated circuit distributed amplifiers (DAs). The method has been applied on both MESFET and HBT DAs. It has been shown that the complexity of the obtained formulas is much less than that of the previously published literature. The results of the new theory are then compared with that of the previous theories and it has been shown that the results exactly match.
