    This paper presents a new voltage/current-mode universal filter using single fully differential second generation current conveyor (FDCCII). The topology can be realized both voltage and current-mode filters such as low-pass, band-pass, high-pass, band-stop and all-pass filtering functions without changing circuit topology. The circuit employs one FDCCII, two capacitors and two resistors. The performance of proposed circuit is confirmed using PSPICE simulations with a standard 0.35 \mum CMOS process.

    This paper presents a new fully differential second-generation current conveyor (FDCCII) using multiple-input bulk-driven dynamic threshold voltage MOS transistor (MIBD-DT MOST) technique. This FDCCII, the MOST techniques such as the multiple-input (MI), bulk-driven (BD) and dynamic threshold voltage (DT) have been used. The MIBD can be reduced the number of differential pair of FDCCII and the DT-MOST technique can be reduced the power supply requirement. Thus, the proposed FDCCII is capable to working with a supply voltage of 0.3 V and it consumes a 0.132 uW of power dissipation. The simulations were performed with SPICE program using the 0.18 um CMOS technology. To prove the workability of the new circuit, the proposed FDCCII has been used to realize universal filter.

    This paper presents a multiple-input multiple-output universal biquadratic filter using differential difference transconductance amplifiers. The variant filtering responses can be obtained by appropriately applying input signals and appropriately choosing output terminals. The voltage-mode filter possesses both high-input and low-output impedances. The proposed filter provides five standard filtering responses. The natural frequency can be controlled electronically, and the quality factor can be controlled orthogonally. The performance of the proposed filter is confirmed using PSPICE simulation based on 0.18 µm CMOS technology from TSMC.

    This paper presents a new current-mode first-order universal analog filter using current-controlled current conveyors (CCCIIs). The proposed circuit can realize first-order sections such as all-pass, low-pass, high-pass filters with both non-inverting and inverting transfer functions into single topology. The pole frequency of these filters can be controlled electronically. The output terminals possess high impedance level which is required for cascading of current-mode circuits. The proposed analog filter is verified using SPICE simulation. The CCCII has been simulated using the 0.18 µm CMOS technology with a supply voltage of 1.8 V. The simulation result can show that it agrees well with theory.

    This paper presents a new mixed-mode universal biquad filter based on differential difference transconductance amplifiers (DDTAs). This work will be expressed that many filtering functions with electronic control of the natural frequency can be obtained using DDTA-based circuit. The topology provides voltage-mode (VM), current-mode (CM), transimpedance-mode (TIM), transadmittance-mode (TAM) transfer functions into single topology and each transfer function offers five standard filtering functions. The performance of the proposed topology is carried out using PSPICE simulators based on 0.18 μm CMOS technology from TSMC. The simulation result shows that it can confirm the proposed topology.
