ANALYSIS OF DIFFERENT STRATEGIES FOR CIRCUIT OPTIMIZATION

Alexander Zemliak, Fernando Reyes Cortés

Resumen


Abstract

The process of analog circuit optimization is defined mathematically as a controllable dynamical system. In this context, we can formulate the problem of minimizing the CPU time as the minimization problem of a transitional process of a dynamical system. To analyse the properties of such a system, we propose to use the concept of the Lyapunov function of a dynamical system. This function allows us to analyse the stability of the optimization trajectories and to predict the CPU time for circuit optimization by analysing the characteristics of the initial part of the process.

Keywords: Circuit optimization, control theory, Lyapunov function, minimal-time system design, time-optimal strategy.


ANÁLISIS DE DIFERENTES ESTRATEGIAS PARA LA OPTIMIZACIÓN DE CIRCUITOS


Resumen

El proceso de la optimización del circuito analógico es definido matemáticamente como un sistema dinámico controlable. En este contexto, podemos formular el problema de minimizar el tiempo de la CPU como el problema de minimización de un proceso de transición de un sistema dinámico.  Para analizar las propiedades de tal sistema, proponemos de usar el concepto de la función de Lyapunov de un sistema dinámico. Esta función permite analizar la estabilidad de las trayectorias de optimización y predecir el tiempo de la CPU para la optimización del circuito analizando las características de la parte inicial del proceso.

Palabras Claves: Diseño del sistema en el tiempo mínimo, estrategia óptima en el tiempo, función de Lyapunov, optimización del circuito, teoría de control.
