2.4-GHz CMOS Power Amplifier With Common-Mode Self-Rejection Technique to Suppress Even Harmonics

IEEE Access
In this study, we propose a common-mode self-rejection (CMSR) technique to improve the linearity of CMOS differential power amplifiers. The proposed CMSR technique is implemented through a matching network consisting of a Guanella transformer between the
