A 1.4V 25mW Inductorless Wideband LNA in 0.13¿m CMOS

Abstract

A 1.4V wideband inductorless LNA, implemented in a 0.13μm CMOS process, consumes 25mW and occupies 0.019mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . Measurement results show 17dB voltage gain, 7GHz BW, 2.4dB NF at 3GHz, -4.1 dBm IIP3, and -20dBm P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1dB</sub> . A common-drain feedback circuit provides wideband 50Omega input matching and partial noise cancellation. A current reuse technique improves both gain and power.
