摘要
An error-feedback transmitter includes an input that receives an input signal, and an output that produces an output signal. It also includes an amplifier, located on a main path that carries a main signal between the input and the output. The transmitter includes a feedback path that carries a feedback signal from the output to the input, and a feedback-signal combiner, located on the main path between the input and the amplifier. The feedback-signal combiner negatively combines the feedback signal with the input signal to improve linearity in the output signal. The transmitter includes a feedforward path that carries a feedforward signal from the input toward the output, and a feedforward-signal combiner, located on the feedback path between the output and the feedback-signal combiner. The feedforward-signal combiner negatively combines the feedforward signal with the feedback signal to suppress components of the main signal in the feedback signal.
