Abstract

The sensitivity of the response of a network to component tolerances is an important practical consideration in the design of active RC networks. Deviations from the nominal element values can distort the response and result in an undesirable or unstable circuit.In order to evaluate the sensitivity of the network a measure should be defined. In order for the measure to be practical all parameters variations must be taken into account. In this paper a new multiparameter tolerance measure is introduced.The measure has been applied to evaluate the sensitivity performance of canonical multiple feedback active RC filter with single operational amplifier.The measure proves to be efficient and a very useful tool for comparing networks from points of view of sensitivity.
