Abstract: A novel configuration tor realizing voltage mode (VM) universal biquad filter based on and employing a single four terminal floating nullor (FTFN), a single voltage follower and four passive components has been presented. The circuit has three inputs and one output and supports lowpass (LP), bandpass (BP), highpass (HP), notch and allpass (AP) filtering  signals from the same configuration, besides being free from the component matching conditions. The bandwidth ω0/Q and cut-off frequency ω0 are orthogonally tunable. The circuit has low sensitivity figures and has the additional advantage of being canonical. Simulated results have also been presented.
