Abstract

See full text

A distributed power management apparatus is provided. The distributed power management apparatus includes an envelope tracking (ET) integrated circuit (ETIC) and a distributed ETIC separated from the ETIC. The ETIC is configured to generate a number of ET voltages for a number of power amplifier circuits and the distributed ETIC is configured to generate a distributed ET voltage(s) for a distributed power amplifier circuit(s). In a non-limiting example, the number of power amplifier circuits and the distributed power amplifier circuit(s) can be disposed on opposite sides (e.g., top and bottom) of a wireless device. As such, in embodiments disclosed herein, the ETIC is provided closer to the power amplifier circuits and the distributed ETIC is provided closer to the distributed power amplifier circuit(s). By providing the ETIC and the distributed ETIC closer to the respective power amplifier circuits, it is possible to reduce trace inductance and unwanted signal distortion.
