Cascode Common Source LNA with Inductive Degeneration Topology utilizing Different Output Matching Circuits in 45nm CMOS Technology

One of the most essential component of transceivers is Low Noise Amplifier (LNA). LNA is placed at the initial stage of the receivers and hence, it governs the overall performance of the receiver. This paper compares Cascode Common Source LNA with Inductive Degeneration Topology utilizing different output matching circuits. We list the specific application domains of the different circuits analyzed, on the basis of the results obtained through simulations. We further conclude that RLC circuit is the best one to be used as an output matching network in terms of minimum power consumption and highest linearity.
