摘要/Abstract：

This paper presents a 37-to-41.8 GHz low-noise amplifier (LNA) with $\mathrm{d}\mathrm{o}\mathrm{u}\mathrm{b}\mathrm{l}\mathrm{e}-\mathrm{g}_{\mathrm{m}}$-boosting technique using quadruple-coupling transformer (QCT) to enhance performance in terms of noise figure (NF) and linearity while reducing power consumption and chip area. The proposed twostage LNA consists a common-gate (CG) single-end cascode input stage for high gain and a common-source (CS) crosscoupled differential amplifier as output stage to improve the overall linearity. The chip is fabricated in 65nm CMOS process, exhibiting a2.9 dB minimum NF, 19.3dB peak gain and 4.8 GHz bandwidth (BW) from 37 to 41.8 GHz. The LNA consumes only 6 mW with chip area of 0.11 $\mathrm{m}\mathrm{m}^{2}$. To the best knowledge of the authors, the work achieves the lowest $\mathrm{N}\mathrm{F}_{\min}$ among LNAs at similar frequency band in bulk CMOS technology so far.
