Design and Analysis of Cascode LNA for 60 GHz Wireless Applications

Abstract

Design methodology and analysis of a 60GHz-band Low Noise Amplifier (LNA) is presented in this paper. The LNA has been designed and simulated using source degenerated cascode topology in 90 nm CMOS for operation at 60 GHz. The structured LNA is minimized for its area with 50%. The designed LNA is computed with ADS and is verified its functionality in terms of Noise Figure (NF), Gain, Linearity, Power dissipation and Stability. The designed LNA uses 12 mW of dc power from a 1.5 V supply with 16.3 dB gain and a NF of 3.5 dB at 60 GHz. The designed LNA is unconditionally stable and has IIP3 of -9 dBm with FoM of 15.
