Abstract :
This paper presents a new voltage-mode universal biquadratic filter using operational transresistance amplifiers as active building block. The proposed circuit offers the following attractive advantages: realization of highpass, bandpass, lowpass filters, simultaneously, from the same circuit, no requirements for component-matching conditions for realizing all filtering function, low active and passive components. The workability of the proposed filter has been confirmed by PSPICE simulators.
