摘要: In this paper the new type of UWB LNA is presented. The amplifier has a novel feedback topology and load circuit that allows designer to obtain high voltage gain matching in wide frequency range from 3.1 GHz 10.6 without cascading, current reuse technique an additional circuit. key point source degeneration with resistive shunt series based on combined parallel-series resonance 11 dB, better than −10 noise figure lies between 3.2 4 dB whole range. value CP1dB −15 at near amplitude response maximum 7.6 GHz. consumes power 11.5 mW supply 1.8 V. These characteristics are obtained by simulation using Virtuoso custom design platform, Cadence Design Systems, 0.18 um CMOS parameters.
