Multiparameter sensitivity in active RC networks

A new statistical multiparameter measure of sensitivity is presented. The new measure realistically accounts for component tolerances and component tolerance correlations and is shown to be particularly useful in the design of integrated circuits. For illustration the measure is used to analyze several high-
Q
low-sensitivity networks. It is shown that for high-
Q
networks the new measure is readily interpreted in terms of the
Q
and center frequency sensitivities of the circuit elements. The measure is also generalized for high-
Q
analysis to account for the error in realization due to the ampliler pole as well as the element variations. This enables an evaluation of the circuit response versus center frequency to be performed.
