This brief describes a novel Wideband Pre-Distortion (WPD) mechanism as a linearization technique for bandwidth-limited CMOS power amplifiers (PAs). The WPD comprises a common-source amplifier and a hybrid feedback mechanism blended with both active and passive networks to secure a flat gain respons...
