摘要

An electronically tunable universal voltage-mode biquad filter which is based on using the newly introduced active building block, namely differential difference current conveyor transconductance amplifier (DDCCTA) is presented in the present paper. The proposed circuit having single input and five output (SIFO) terminals uses two DDCCTAs, two grounded capacitors and two electronic resistors suitable for MOS-C realization. The circuit realizes all the five standard biquadratic filter functions simultaneously without changing circuit topology. In addition, the circuit features the high-input impedance terminal, an electronic control of its natural angular frequency and quality factor. The workability of the proposed circuit has been verified using PSPICE simulations based on CMOS DDCCTA implemented in 0.5 μm MIETEC CMOS technology.
