Influence of Current Reuse LNA Circuit Parameters on its Noise Figure

Abstract

A 2.4 GHz low noise amplifier (LNA) with a bias current reuse technique is proposed in this work. To obtain the optimum noise figure (NF) value, dependence of NF on its most influential LNA parameters has been analysed. Taking into account the LNA design requirements for other figures of merit, values of the circuit parameters are given for the optimum noise figure.
