Abstract
In most applications using the feedforward linearization technique, the overall amplifier efficiency is of significant concern. This paper theoretically analyzes the effect that the insertion loss of the time delay elements has on the overall efficiency of a feedforward amplifier. Practical linearity and efficiency results are given for a feedforward system, using VMOS transistor class C main and error amplifiers, to illustrate the effectiveness of the analysis
