Abstract
Transmitters and methods of transmitting a polar-modulated signal include a driver to output a polar-modulated signal according to a phase-modulation signal and an amplitude-modulation signal. A voltage regulator is connected to the driver, with the amplitude-modulation signal controlling an input of the voltage regulator and with the amplitude-modulation signal further being combined with an output of the voltage regulator to control an amplitude of the output of the driver to compensate for bandwidth cutoff noise in the voltage regulator.
