New multifunction filter using an inverting CCII and a voltage follower
Abstract
A new multifunction filter using minimum components is presented. This filter which possesses single input and four outputs can simultaneously generate second-order highpass, bandpass, and lowpass filtering functions at individual output terminals. The filter has the following merits: uses only two grounded capacitors which makes it suitable for integrated circuit implementation, no matching condition is required, offers multifunction outputs, and has low passive and active sensitivities. Experimental results agree very well with the theoretical result.
