To achieve higher transmitter efficiency, envelope tracking (ET) using supply modulators (SM) is widely used in today’s systems. However, the demands for high bandwidth, complex modulation and multiple access schemes in 5G and upcoming 6G systems have exposed serious limitations of analog ET (AET) that get worse in high-power high-voltage applications, e.g., base-station transmitters. As a promising alternative to AET,
