The Method to Calculate Power Series of Non-linear Transistor Circuit

Analytic method of power series is one of the common methods to solve non-linear transistor circuit. The key of this method is to solve the high degree coefficient of the power series expressed the voltage and current in circuit. In this paper the calculation of the high degree coefficient of the transistor circuit is given. According to this method, the additional sources which express the non-linear transistor circuit are introduced into the transistor's H-parameter equivalent circuit, then we can calculate the high degree coefficient by use of linear circuit theory conveniently, Finally, a practical example is given.
