Different Input Impedance Matching Circuits for Cascode Common Source LNA with Inductive Degeneration Topology in 45nm CMOS Technology

This paper presents various input impedance matching networks that can be used for cascode common source LNA with inductive degeneration topology in 45 nm CMOS technology. We review the matching networks being used and analyze their performance using simulations. Based on our simulation results, we further conclude that T-Matching network is the best input impedance matching network for cascode common source LNA with inductive degeneration topology in 45 nm CMOS technology.
