Abstract
An active RC filter circuit is described which realizes second order lowpass and bandpass functions. The filter uses two I.C. Operational amplifiers and four passive components to achieve accurate Q values up to 50. Its Q sensitivity to component values is found to be very low. The results of an exhaustive computer simulation are given which clearly define the operating limits of the circuit. A practical design technique is outlined, and a sixth order example is given.Keywords
