In this paper a new grounded capacitance multiplier based on DXCCII suitable for operation at low and moderate frequencies is presented. The proposed circuit employs only a single dual-X second-generation current conveyor (DXCCII) active device, used as a voltage amplifier with two NMOS transistors operating in triode region, cooperating with a floating capacitor. The realized equivalent capacitance obtained from Miller multiplication of the reference capacitor and its multiplication factor is electronically tunable. Simulation results using AMS 0.35 mu m CMOS process technology parameters are included. Functionality of the proposed circuit is verified through its application in a G(m)-C second-order low-pass filter.
