NEW MULTIFUNCTION FILTER USING AN INVERTING CCII AND A VOLTAGE FOLLOWER

A new multifunction filter using minimum components, is presented. Thi s filter which possesses single input and four outputs can simultaneou sly generate second-order highpass, bandpass, and lowpass filtering fu nctions at individual output terminals. The filter has the following m erits: it uses only two grounded capacitors which makes it suitable fo r integrated circuit implementation, no matching condition is required , offering multifunction outputs, and has low passive and active sensi tivities. Experimental results agree very well with the theoretical re sult.
