Apparatus, systems, and methods are provided for controlling the output of a transmitter using a digital error signal. A method comprises generating a digital reference signal based on a baseband input signal and converting the digital reference signal to an analog reference signal. The method further comprises generating an analog error signal in response to a difference between the analog reference signal and an analog output signal. The method further comprises generating a digital error signal from the analog error signal, and generating an input signal for the transmitter based on the baseband input signal and the digital error signal.
