Much research has been devoted to the design of active filters with reduced dependence on the active devices; however no general analysis scheme or method of comparing existing filters has emerged. A general characterization of second-order active-RC filters employing one, two, and three operational amplifier(s) is given. A method of comparing active filters with respect to the active devices based on the active sensitivity function is introduced. Conditions necessary for zero pole, ωo, Q, and transfer-function-magnitude active sensitivities are derived. Several novel circuits that possess these zero-active-sensitivity properties are presented. The markedly superior performance of these filters is demonstrated by a comparison of second-order zero-active-sensitivity filters with other popular existing realizations. Experimental results that agree favorably with the theoretical results of these filters are presented.doctoral dissertationsengCopyright and other restrictions may apply.
