Abstract

Class-E amplifier is one of the switching amplifiers. It is difficult to determine the circuit parameters satisfying the switching conditions. Although the Newton method was proposed to determine the passive elements, it requires a good initial solution that is obtained by using an analytical expression of the class-E amplifier. Even if the circuit configuration is slightly changed, the analytical expression must be re-derived. In this paper, the passive element value determination of class-E amplifier is defined as an optimization problem. This problem is solved by some methods which do not rely on the initial solution obtained by using the analytical expression. Furthermore, the objective function value for the optimization is efficiently calculated via a behavioral model of the class-E amplifier, which eases the optimum circuit design computationally and economically. Thus, an automated design procedure for the class-E amplifier will be presented in this paper.
