Abstract :
In this paper a study is made of methods which may be used to modify the design of an active RC filter to compensate for the effects of operational amplifier gain bandwidth. The technique is applied to adjust the element values of an infinite-gain multiple-feedback low-pass active-RC filter. Sixty-five different possible compensation methods are identified. Of these twelve are shown to produce useful results
