Analogue circuit optimization process may be controlled using a generalized design methodology. Lyapunov function is an integral function that carries information on this process. The use of Lyapunov function concept for a dynamic system allowed for comparison of various design strategies with respect to their stability and convergence. Study of Lyapunov function’s and its derivative’s behavior allowed for revealing significant correlation between this function’s properties and processor time for circuit design. Analysis of processor time dependence on control vector switching points provided a possibility to find this vector’s optimal structure. Numerical results prove bright future of such approach for finding quasi-optimal algorithm of analogue circuits design.
