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 design currentmode first-order continuous-time analog filters. Parameter tunability is achieved by the use of a two-MOSFET electronic resistor which exhibits variation in resistance in accordance with a control voltage. The proposed circuits are amenable for monolithic integration by virtue of the fact that only MOSFETs and grounded capacitors are utilized. Circuit simulations using PSPICE yielded promising results.
