Mohd. Zihaib Khan, Mohd. Samar Ansari . DVCC-based Electronically Tunable First-Order Current-mode Filters. International Journal of Computer Applications. 48, 15 ( June 2012), 21-24. DOI=10.5120/7425-0415
The advent of differential voltage current conveyor(DVCC) has opened up new avenues in analog circuit design. In the present work, a DVCC has been employed to designcurrent-mode first-order continuous-time analog filters. Parameter tunability is achieved by the use of a two-MOSFET electronicresistor which exhibits variation in resistance in accordancewith a control voltage. The proposed circuits are amenable formonolithic integration by virtue of the fact that only MOSFETsand grounded capacitors are utilized. Circuit simulations usingPSPICE yielded promising results.
