A 0.5-6 GHz Improved Linearity, Resistive Feedback 90-nm CMOS LNA

This paper presents a resistive feedback broadband LNA in 90 nm CMOS which occupies 50 mum times 270 mum of active area. The LNA has 7 GHz 3 dB bandwidth and >24 dB voltage gain. Across 0.5-6 GHz, its input matching is better than -10 dB, noise figure below 2.5 dB, and iIP3 better than -8 dBm. Techniques to improve linearity in resistive feedback LNAs are discussed in detail. The LNA also provides an additional low power mode operation.
