Abstract

A low noise amplifier (LNA) is provided for a first block of a wireless receiver in a wireless communication system using CMOS technology. The LNA includes a first cascode amplifying module and a second cascode amplifying module, where an output signal of the first cascode amplifying module is fed to the second cascode amplifying module in order to cancel third-order intermodulation frequencies (IM3), such that input-referred third-order intercept point (IIP3) is increased and thus linearity of the LNA is improved.
