概要	The noise performance of common source and cascode topology 60 GHz LNAs is analyzed and verified. The analysis result shows that the noise performance of the cascode topology is degraded at high frequency due to the inter-stage node capacitance. Theanalysis result is verified by　experimental results. A three-stage LNA employing two noise-matched CS stages and a cascode stage is proposed. For comparison a conventional two-stage cascode LNA isalso been studied with the measurement-based model. The measuredresults of the proposed LNA show thatan input and output matching of less than -10 dB, a maximum gain of 9.7 dBand a noise figure (NF) of 3.2 dB areobtained with a power consumption of 30 mW from a 1.2-V supply voltage. Compared to the conventional cascode LNA, an improvement of 2.3-dB for NF and 1.9-dB for power gain are realized. Both the proposed and　conventional LNAs are implemented in 65 nm CMOS process. 主筆
