Fecha de publicación: 08/11/2012 Fuente: Wipo "digitalization" Embodiments disclosed in the detailed description relate to a pseudo-envelope follower power management system including a parallel amplifier and a switch mode power supply converter cooperatively coupled to generate a power supply voltage at a power supply output coupled to a linear radio frequency power amplifier. The parallel amplifier output is in communication with the power amplifier supply output. The parallel amplifier governs operation of the switch mode power supply converter and regulates the modulated power supply voltage base on a VRAMP signal. The parallel amplifier circuit includes a linear regular to provide an output current to regulate the power supply output when the parallel amplifier and switcher mode power supply converter are disabled in a low power modulation mode.
