Influence of current reuse LNA circuit parameters on its noise figure [PDF]
Serbian Journal of Electrical Engineering, 2009 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 analyzed. Taking into account the LNA design
