Original Abstract

This paper presents two low-power voltage-mode multifunction biquadratic filters using differential difference current conveyors (DDCCs). Each proposed circuit employs three DDCCs, two grounded capacitors and two grounded resistors. The low-voltage ultra-low-power DDCC is used to provide low-power consumption of the proposed filters. By appropriately connecting the input and output terminals, the proposed filters can provide low-pass, band-pass, high-pass, band-stop and all-pass voltage responses at high-input terminals, which is a desirable feature for voltage-mode operations. The natural frequency (wo) and the quality factor (Q) can be orthogonally set by adjusting the circuit components. For realizing all the filter responses, no inverting-type input signal requirements as well as no component-matching conditional requirements are imposed. The incremental parameter sensitivities are also low. The characteristics of the proposed circuits are simulated by using PSPICE simulators to confirm the presented theory.
