Abstract
This paper presents an analysis that accounts for the effect of standard ESD structures on critical LNA specifications of noise figure, input matching and gain. A common-source-cascode CMOS RF LNA is used for this analysis. It is shown that the ESD structures degrade LNA performance particularly for higher frequency applications. The analysis has been validated with SpectreRF simulations for a 0.25-μm CMOS process. Design techniques are also proposed for designing LNAs with ESD protection.
