Abstract

LNA millimeter-wave simultaneous noise and impedance matching source degeneration Electrical and Electronic Engineering
This paper presents analysis and design of source inductance for multistage LNA at 77-GHz band in 90 nm CMOS technology. Instead of simultaneous noise and impedance matching, the analysis shows the optimum degeneration of the single stage design for millimeter-wave frequencies. A low-power 77-GHz band LNA has been demonstrated to verify the optimization result. By using the proposed method, the LNA exhibited a low noise figure of 5.1 dB and a gain of 18.1 dB at 78.5 GHz with only 8 mW from a 1-V power supply.
