Abstract :
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 -7dBm at 0.8 GHz, and the power consumption is 6.5mW with a 1.8-V supply voltage.
