Amplifier linearization of using non-standard feedback

摘要

I will provide an amplifying device. The first amplifier, the second amplifier, the first sensor, pre-distortion component of the first, and the amplification device has a signal combiner. The first amplifier to generate a second signal by amplifying the first signal. The first sensor to generate a third signal based on the second signal. It is turned on when the amplitude of the fourth signal exceeds the threshold amplitude, generating a fifth signal by amplifying the fourth signal, the second amplifier, threshold amplitude is less than the amplitude of the fourth signal It is turned off if it is. Based on the first input signal, and, based on the third signal, and, based on the on and off states of the second amplifier, pre-distortion component of the first, generates a first signal to. Signal combiner outputs the output of the amplifier based on a fifth signal and the second signal.
