Abstract
A 3-terminal operational filter circuit is presented that can be used to construct various types of active filters. The filter circuit can be used to construct various orders of low pass, band-pass, high pass, and notch filters by simply coupling a few circuit elements (e.g., resistors and capacitors) to the filter circuit terminals. By cascading filter circuits, various types of higher order filters can constructed. The filter circuit can be manufactured with particular internal resistance and capacitance to enable the circuit to operate within a selected range of center frequencies. Users can then select a particular center frequency, notch frequency, quality factor, and gain of the filter circuit by selecting particular values for the circuit elements coupled to the filter circuit terminals.
