Abstract
In this paper, noise analysis for a low noise transconductance amplifier (LNTA) is performed. LNTA becomes popular and necessary as the high linearity requirement and low supply voltage trend make the RF front-end design go into current domain. Common-gate common-source (CG-CS) topology is examined for noise analysis. Via theoretical analysis and specific equations derived, this paper not only studies how to arrange the topology and how to choose the design parameters, but also discusses the tradeoffs existing in LNTA design between noise figure, input matching and linearity.
