Abstract
In this paper, multiple-output multifunctional biquadratic filters using current differencing buffered amplifiers (CDBAs) as active elements are presented. The proposed circuit topologies are mainly composed of the CDBA-based cross-coupled feedback configuration and the voltage substractor. By an appropriate choice of virtually grounded passive components, the configurations can simultaneously realize lowpass, highpass, bandpass, bandstop and allpass voltage transfer functions, all at low resistance outputs. The natural angular frequency and the quality factor can orthogonal controllable. PSPICE simulation results demonstrating the feasibility of the technique are also included.
