چکیده
In this paper, a digitally programmable single input multi-output voltage mode multifunctional biquadratic filter has been presented. The circuit employs three differential voltage current conveyors (DVCC), two grounded capacitors, two grounded and two floating resistors. The digital re-configurability is obtained using a current-summing network (CSN). Cut-off frequency is controlled and varied with the help of a 3–bit digital control word. PSPICE simulations using TSMC 0.25μCMOS technology have been performed to validate the theoretically predicted results.
