Abstract :
An algorithm for multiparameter sensitivity analysis of a synthesized network based on a nullor model of active devices is implemented. It is simplified by using the modified Coates flow-graph. Due to the suggested method, additional information for parameter influence upon transmission coefficients in the circuit is obtained, all partial transfer functions and their products can be found. An example on symbolic analysis of universal filter with the operational transresistance amplifier model is given in order to show the usefulness of the proposed symbolic method for multiparameter sensitivity analysis based on the nullor model.
