Abstract: An operational transconductance amplifier (OTA) based voltage-mode universal filter is presented. The proposed circuit employs four OTAs with two grounded capacitors and realizes lowpass, bandpass and highpass filter functions. The pole-frequency wp and pole-Q, Qp are orthogonally adjustable by proper choice of transconductance gains of OTAs and capacitor values. The proposed universal filter can also be used for the realization of notch filter function. In addition a current feedback amplifier (CFA)-based universal filter is also realized by converting the OTA-based circuit using standard tranformation method1 [Hou C L & Wang W Y, IEE Proc Circuits Devices and Systems, 144, 209-212.]. Both the circuits have been studied in detail. The simulation results have also been included.
