An Envelope Tracking Supply Modulator Utilizing a GaN-Based Integrated Four-Phase Switching Converter and Average Power Tracking-Based Switch Sizing With 85.7% Efficiency for 5G NR Power Amplifier |
Abstract | ||
---|---|---|
This article proposes a supply modulator (SM) that uses high switching frequency gallium-nitride (GaN) devices to achieve a four-phase fast step-down converter for the fast-tracking ability of the envelope tracking (ET). The ET signal is reshaped to generate an average power tracking (APT)-based signal to control the size of GaN switches to further increase light-load efficiency due to reduced swi... |
