Many circuits with different configurations have been proposed for LNA, in different applications.
Wideband input matching is possible for CG configuration and hence this configuration is widely used in broadband LNA circuits [7], [8]. However CS configuration may be used in wideband applications using special feedback or matching circuits. Inductive source degenerated CS configuration is conventionally used in narrowband LNA circuits [9].
