Computer Aided Design of GaAs Mesfet Power Amplifiers

Computer aided design techniques for non linear circuits, such as microwave GaAs MESFET power amplifiers, are actually too time expensive due to the large computer time necessary for each non IL: ear analysis. A new algorithm is proposed in which every directional search for the minimum in the optimization procedure is based on a gradual step-by-step perturbation of the electrical system which is analyzed by a harmonic balance technique. This algorithm allows for a great reduction in the computing time.
