Abstract:
This article presents a high-voltage symbol-power-tracking supply modulator (SPT-SM) that delivers a wide output range for 5G gallium nitride (GaN) power amplifiers (PAs). To enhance the output voltage transition speed, a two-step subranging dynamic voltage scaling (DVS) scheme and an inductor current slew-rate enhancement technique are proposed. By partitioning the …
