Chapter

Abstract

The chapter deals with economic realizations of second-order active RC filters employing a single differential input operational amplifier as the active element. All the basic types of filters are considered and the sensitivities of Q and undamped natural frequency with respect to various parameters are evaluated. Further, it is shown that one circuit configuration can lead to several types of filter realizations having the same Q, simply by short circuiting or open circuiting certain elements, thereby reducing the manufacturing cost.
