Amplifier Linearization By Complementary Pre Or Post Distortion (1976)
By A. Prochazka, P. Lancaster, and A. Neumann, Delta-Benco-Cascade Ltd.
A technique of amplifier linearization through the use of complementary pre or post distortion correction circuits is investigated. Using the Volterra series representation distortion cancellation constraints imposed on the correction circuit are derived. A simple distortion correction circuit consisting of a diode, a resistor and a capacitor (inductor) is then devised to meet the above constraints for cancellation of the amplifier's third order distortion products.
A theoretical analysis of distortion generated 'in both a single stage transistor amplifier and a complementary distortion correction circuit (C.D.C.C.) is carried out to verify the realizability of this linearization technique.
