A new current-mode universal filter is presented. The proposed filter uses three four-terminalfloating nullors (FTFNs), three grounded capacitors, and four grounded resistors. The proposedfilter has three inputs and one output and can realize lowpass, highpass, bandpass, notch, andallpass transfer functions without changing the circuit topology. The proposed filter enjoys lowactive and passive sensitivities and independent control of the parameters ω0 and ω0Q0 using grounded elements
