چکیده
This paper proposes a wideband common-gate LNA using capacitive feedback. The transconductance of the proposed LNA can be enlarged and noise figure can be improved while the conventional common-gate LNA has to use a smaller transconductance for the input impedance matching. In the experimental results using a 0.18-μm CMOS technology, the gain is 13.4 dB, NF is 2.7 dB, IIP3 is −7 dBm at 0.8GHz, and the power consumption is 6.5mW with a 1.8-V supply voltage.

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...
