Abstract:

This paper presents a novel amplifier linearization technique based on negative impedance compensation with expansion of Volterra series. All amplifiers possess the property of distorting the signals they are required to amplify. Distortion is caused due to nonlinearity of the amplifiers. Demonstration of Volterra model, the proposed technique is suitable for linearizing amplifiers with distortion analysis, which is more intuitive and flexible than traditional method. Class F amplifier implemented with proposed linearization technique and simulation results show high linearity, power added efficiency, inter modulation distortion and high gain accuracy has been achieved.
