چکیده
In this paper, we present a 0.7 V low-noise amplifier(LNA) using monolithic transformer feedback to neutralize the gate-drain overlap capacitance of a field-effect transistor(FET). It is a single-ended amplifier implemented in 0.18-μm CMOS technology designing for 5-GHz wireless local-area networks (LANs). This LNA achieves a simulated power gain of 10.84 dB, noise figure(NF) of 2.4 dB, and input referred 1 dB compression point (P1 dB) of −8 dBm at 5.8GHz. Operating from a 0.7-V supply, the power consumptions for the low noise amplifier(LNA) are 4.8mW. DOI: 10.2529/PIERS060907035333

متن کاملA New Ultra-Wideband Low Noise Amplifier With Continuous Gain Control
This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...
