This paper presents a modified post-distortion (PD) linearization technique for cascode common-gate low noise amplifiers (CG-LNAs) working at high frequencies up to millimeter-wave band. utilizes an auxiliary transistor together with inter-stage inductor suppress the third order distortion without degrading gain. The input intercept point (IIP3) of linearized CG-LNA is improved by factor 12 dB. For demonstration, mm-wave differential was fabricated based on 65-nm CMOS process. It achieves...
This letter presents a concurrent dual-band low-noise amplifier (LNA) operating at 28 and 39 GHz for multiband 5G wireless systems. In order to achieve wideband input power matching, the LNA adopts shunt-series feedback structure. Detailed noise analysis of transformer is proposed guide noise-optimized design, modified network improve matching. The method also enhances transconductance stage, thus suppressing subsequent circuit obtaining better overall figure (NF). Based on this structure,...
