Abstract
A technique that reduces or eliminates trading-off power amplifier efficiency and costly external filtering in amplitude and phase modulated sinusoidal signal generation uses multi-phase outphasing and a multi-phase switching mode power amplifier to generate the amplitude and phase modulated sinusoidal signals. The technique combines multiple clock phases with sinusoidally weighted circuits of the switching mode power amplifier to improve amplitude and phase modulated sinusoidal signal generation.
