Performance benchmark of State-of-the-art Sub-6-GHz wideband LNAs Based on an Extensive Survey
Résumé
This work presents a survey based on more than 200 published papers related to sub-6 GHz wideband LNAs [1]. It investigates the trends with respect to the technology node. Moreover, it proposes a comparison between the most used topologies regarding their main performance metrics such as the gain, bandwidth, noise figure, power consumption and linearity. Based on this study, analytical predictions can be verified and appropriate architectures targeting a given set of specifications can be easily selected. The analysis highlights also the performance improvements and design trade-offs of design enhanced solutions such as noise cancelling and gm-boosting architectures.
