Abstract:
Apparatus and methods for capacitive load reduction are disclosed. In one embodiment, a power amplifier system includes an envelope tracker configured to provide a supply voltage to a plurality of power amplifiers. The power amplifiers include power supply inputs electrically connected in a star configuration so as to reduce a capacitive load of the envelope tracker. The distributed capacitance of the power amplifiers is used to provide RF grounding so as to reduce the size of or eliminated the use of bypass capacitors.
