Abstract :
Noise performance is the most important property of any low noise amplifier. Different conventional cascode ultrawideband 3.1-10.6 GHz low noise amplifier (LNA) topologies have been studied and compared in terms of noise figure (NF). The effect of an inductive inner stage on noise has been discussed. A novel two by two linear correlated matrix has been assumed for deriving correlation impedances of the Noise Figure. All simulations are based on a typical 0.18-mum CMOS process.
