Abstract
The paper presents a new Multi Inputs and Single Output (MISO) VM Universal Biquadratic Filter (UBF) employing only two low voltage dual output current conveyors (DOCCIIs) along with two resistors and two capacitors. The proposed circuit realizes six standard biquadratic responses, viz., low pass high pass, non inverting band pass, inverting band pass, band elimination and all pass. The filter enjoys attractive features, such as, low active and passive component count, low sensitivity performance, operation of low supply voltage (+/- 0.75V) and power consumption of 3.2 mW. The filter was designed and verified using PSPICE with convincing results.
