Abstract
A power train amplification stage is described. The power train amplification stage includes a power amplifier. The power train amplification stage also includes a switched mode power supply that provides a bias voltage to the power amplifier. The power train amplification stage further includes a pulse density modulator. The power train amplification stage also includes a feedback path from the power amplifier to the pulse density modulator.
