Abstract

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.
