Abstract
This paper presents a new voltage-mode universal filter with three-input and four-output using two differential difference current conveyors, two grounded capacitors and two resistors. The proposed filter is suitable for integrated circuit by using only grounded capacitor. Low-pass, band-pass, high-pass and band-stop voltage responses can be obtained simultaneously into one single topology and without component-matching condition requirements. The natural frequency and the quality factor can be controlled orthogonally by setting the passive components. PSPICE simulation results using 0.5 μm CMOS technology form MIETEC are included to confirm the theoretical analysis. The simulation results can be expressed that the proposed circuit agrees well with theory.
