This paper presents two fully integrated 60 GHz single stage low noise amplifiers for wireless applications using the cascode topology. The two different amplifiers have been optimized for different purposes, one for low noise and the other for high gain. They are implemented in a 90 nm low power CMOS technology. The matching networks have been realized using shielded coplanar transmission lines. The low noise stage achieves 5.6 dB small signal gain and 7.5 dB noise figure, while the gain stage reaches 7.1 dB small signal gain and 8.5 dB noise figure. Both the stages consume approximately 7 mW. The detailed design procedure and the achieved measurement results are presented in this work.
