Generalized optimization methodology of second level for system design

The new general methodology for the analog system optimization was elaborated by means of the optimum control theory formulation in order to improve the characteristics of the system design process. A special control vector is defined to redistribute the compute expensive between a network analysis and a parametric optimization. This approach generalizes the design process and generates a set of the different optimization strategies that serves as the structural basis to the optimal design strategy construction. The principal difference between this new methodology and before elaborated theory is the more general approach on the definition of the system parameters and more broadened structural basis. The main equations for the system optimization process were elaborated. These equations include the special control functions that generalize the total system optimization process. Numerical results that include as passive and active nonlinear networks demonstrate the efficiency and perspective of the proposed approach.

Circuit Design Process as a Controllable Dynamic System

The formulation of the process of analog circuit design has been done on the basis of the control theory application. This approach produces the set of different design strategies inside the same optimization procedure. Basic equations for this design methodology were elaborated. The problem of the time-optimal design algorithm construction is defined as the problem of a functional minimization of the optimal control theory. By this context the design process is defined as a controllable dynamic system. Numerical results of some electronic circuit design demonstrate the efficiency of the proposed methodology and prove the non-optimality of the traditional design strategy.
