Abstract :
Three new electronically tunable filter configurations which employ only one current controlled differencing buffered amplifier (CDBA) are proposed. The proposed filters operate in voltage-mode (VM) and use three passive elements. Each proposed filter can realize one of the band-pass, low-pass or high-pass responses. The parameters omega 0 and omega0/Q enjoy independent electronic tunability. Effect of the non-idealities and the sensitivity analysis of the proposed filter are also examined. The validities of the proposed filters are verified through PSPICE simulations
