Abstract

A highly linear complementary source follower (CSF) feedback CMOS wideband LNA is implemented as a part of a highly linear receiver front end resilient to 0-dBm out-of-band blockers. Due to the linear feedback operation of the CSF, the proposed LNA greatly improves large-signal linearity performances compared to the conventional SF feedback LNA. The proposed feedback LNA shows an input P_1dB close to 0 dBm while achieving an input reflection coefficient less than -10 dB, an average power gain of 10 dB, and a minimum noise figure of 3 dB. The power consumption is 18 mW at a 2-V supply voltage.
