This paper presents the design of a CMOS variable gain low noise amplifier used for ultra wideband applications. A current reuse technique is applied to the resistive feedback amplifier to widen the gain tuning range. A common source amplifier is cascoded to achieve high gain and gain controllability. The LNA is designed to operate at 1.4V supply voltage and is implemented in TSMC 0.18µm CMOS technology...
This paper presents design technique of CMOS based UWB low noise amplifier using active shunt feedback technique at 0.18µm technology. The proposed low noise amplifier is able to provide high gain with flatness at ultra wideband (UWB) range, which yet consumes small power with simple and compact design model. This LNA is implemented using Cascode amplifier topology with active shunt feedback to fulfill...
This paper presents a 3–9 GHz CMOS low noise amplifier (LNA) designed in a 0.18 μm CMOS technology which uses negative feedback with magnetic coupling at the input of a common source-LNA instead of resistive feedback. Using the proposed topology, power gain of 14.1±1 dB and noise figure between 2.24–2.45 dB was achieved in a bandwidth (BW) of 3–9 GHz. The total drawn power of the proposed circuit...
