About linearization of broadband amplifier by feedback (new opportunity of the well known method)

Abstract

With a view to increase linearity of an amplifier it is proposed to implement separately two different loops of the negative feedback for the odd and even order components of the signal. It is shown that in this case linearization factors for the third order nonlinear components of these two loops complement (in dB) each other. As a result the amplifier dynamic range can be increased many times. © 2001 IEEE.
