Abstract
Scattering Parameters or S-parameters are complex numbers which tells us about how voltage waves are propagating in the radio-frequency (RF) environment. In this paper common source and other will be the cascoded common gate topologies have been analyzed. Scattering parameter analysis shows that gain and impedance matching is better for CG LNA. S-parameter is an important tool for LNA design, following information can be obtained a) The frequency b) characteristic impedance (often 50 ?) c) The allocation of port numbers d)Operating environment such as temperature, control voltage and bias current.
