摘要

本文首次用公式提出了级联放大器的最佳级间匹配电感。该公式澄清了降低级联放大器增益的场效应管的电容。采用90nm CMOS制作的感应匹配级联码LNA在60GHz时增益为25.6 dB, NF为6 dB，输出P1dB为-2.3 dBm，功耗为26.9 mW。

An optimum inductive matched cascode LNA in 60GHz-band

This paper presents an optimum interstage matching inductor of a cascode amplifier by formulation, for the first time. The formulation clarifies capacitances of FETs which degrade a gain of the cascode amplifier. The inductive matched cascode LNA fabricated by 90nm CMOS performs 25.6 dB gain with NF of 6 dB and output P1dB of -2.3 dBm at 60GHz while consuming 26.9 mW.
