Abstract: 

In this paper a new method for design and realization of a sinusoidal oscillator is proposed. The oscillator has fixed amplitude. As we know the design of this kind of oscillator is very difficult because of its sinusoidal form and fired amplitude. Design is done in state space domain. After designing oscillator is realized base on the concepts of trees and links. In fact we have designed a nonlinear system such that its phase portrait corresponds to oscillation and also prespecified amplitude of the oscillation. Then it is transferred to the time domain. The design of an appropriate nonlinear system is based on the equipotential curves.
