Abstract
This paper presents a new current-tunable current-mode universal biquadratic filter with two inputs and two outputs using one modified current-controlled current differencing transconductance amplifier, two grounded capacitors and one grounded resistor. The proposed circuit provides following advantages: realization of lowpass, bandpass, highpass, bandstop and allpass current responses; orthogonal control of the natural frequency and the quality factor; employment of grounded passive components which is very suitable for integrated circuit implementation; low active and passive sensitivities. Simulation results are also given to confirm the presented theory. © 2012 IEEE.
