Network for cascade compensation of the non-linearity of an amplifier

摘要

A network for compensating the non-linearity of an amplifier has an auxiliary network provided either before or behind said amplifier. This network comprises a first branch for transferring the input signal linearly and with the amplification factor 1 from a branch point to an adder; a second branch comprising at least one cascade network which is composed of the cascade circuit of a circuit component having a transfer function corresponding to the quadratic transfer function of the compensated amplifier and of a circuit component having a transfer function corresponding to the inverse linear component of the transfer function of the compensated amplifier; and/or a third branch comprising a cascade network composed of the cascade circuit of a circuit component having a transfer function corresponding to the cubic component of the frequency dependent transfer function of the compensated amplifier and of a circuit component having a transfer function corresponding to the inverse linear component of the frequency-dependent transfer function of the compensated amplifier.
