The pseudo-envelope follower power management system may include a switch mode power supply converter and a parallel amplifier cooperatively coupled to provide a linear RF power amplifier supply to the linear RF power amplifier. The pseudo-envelope follower power management system may include a charge pump configured to power the parallel amplifier. The charge pump may generate a plurality of output voltage levels. The charge pump may be either a boost charge pump or a boost/buck charge pump. The pseudo-envelope follower power management system may include an offset voltage control circuit configured to provide feedback to the switch mode power supply converter to regulate an offset voltage developed across a coupling device that couples the output of the parallel amplifier to the linear RF power amplifier supply."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Boost charge-pump with fractional ratio and offset loop for supply modulation","description":"Embodiments disclosed in the detailed description relate to a pseudo-envelope follower power management system for managing the power delivered to a linear RF power amplifier.
