CMOS LNA optimization techniques: Comparative study

This paper describes and analyzes two low-noise amplifier (LNA) optimization techniques which are applied to the common-source MOS topology with inductive degeneration. The optimization techniques are consisted of the inductive-specified and the current-specified technique. The purpose of the paper is to provide clear understanding of the design guidelines, limitations and the pros and cons regarding each design technique. LNA examples are designed following the guidelines of each technique using standard CMOS 0.18um process.
