IEEE Transactions on Circuits and Systems I: Regular Papers, 2012•ieeexplore.ieee.orgBurst-mode operation of power amplifiers (PAs) is a promising concept towards higher
power efficiency in radio frequency (RF) transmitters. Such transmitters use pulse-width
modulation (PWM) to create the driving signal for the PA, and a reconstruction filter after
amplification to obtain the transmission signal. However, conventional digital pulse-width
modulated signals contain a large amount of distortion that cannot be removed by the
reconstruction filter in a satisfactory manner.
