A 2.5-W 40-MHz-bandwidth hybrid supply modulator with 91% peak efficiency, 3-V output swing, and 4-mV output ripple at 3.6-V supply

A 2.5-W 40-MHz-bandwidth hybrid supply modulator with 91% peak efficiency, 3-V output swing, and 4-mV output ripple at 3.6-V supply

We describe a supply modulator comprising a proposed delay-based hysteresis controller, proposed wideband class-AB amplifier, and class-D amplifier for an envelope tracking (ET) power amplifier (PA). We investigate the power dissipation and optimization method of the supply modulator for wideband ap...
