A new supply modulator architecture for robust performance against the battery voltage variation is presented. The resulting modulator is an optimized power management integrated circuit (PMIC) for an envelope tracking (ET) power amplifier (PA). The basic topology of the PMIC is based on a hybrid switching amplifier combining a wideband class-AB buffered linear amplifier and a highly efficient switching-mode buck converter in a master-slave configuration. The additional boost converter… CONTINUE READING
