24 GHz LNA in 90nm RF-CMOS with high-Q above-IC inductors

Abstract

K-band RF capabilities of 90nm RF-CMOS combined with thin-film above-IC high-Q inductors is assessed by means of a 24 GHz LNA. The LNA, implemented as a single stage common-source amplifier led to state-of-the art results for CMOS technology at 24 GHz. Record noise figure of 3.2 dB is obtained with a gain of 7.5 dB. Input and output matching are respectively -16 dB and -30 dB. The LNA works with a 1V supply voltage and consumes only 10.6 mA.
