A low noise amplifier for UWB and broadband applications is presented. The active dual loop negative feedback architecture dissevers the severe tradeoff existing between the input impedance, gain and noise figure, and produces a flat S11 across the entire band. The L#A is composed of a voltage amplifying negative feedback amplifier with a transconductance amplifier forming a shunt-shunt feedbac...
