Abstract
This brief provides a brief tutorial on designing a high efficiency envelope-tracking supply modulator with recent techniques. Design challenges for 5G communication applications are given. Detailed techniques covering topology derivation, multi-level and fast-speed switching converter design considerations, voltage step-up and -down function implementations, linear amplifier bandwidth improvements and measurement setup are discussed, providing design guidelines and considerations.
