Abstract

A novel resistive negative feedback wideband low-noise amplifier (LNA) with feedforward noise and distortion cancelation is presented in this paper. In comparison to conventional resistive negative feedback LNA´s the proposed LNA circuit shows improved performance parameters including voltage gain, noise figure (NF) and input-referred third-order intercept point (IIP3). Especially for wideband LNA design´s in deep sub-micrometer CMOS technologies, the proposed noise cancelation is efficient. A testchip is fabricated in 65nm CMOS. Measurement results show an LNA performance of 24dB voltage gain, 2dB NF, -5.5dBm IIP3 and S11<;-10dB over 0.1-4GHz frequency range. The circuit consumes 12mW and the core layout size is 150μm×80μm.
