“…Despite that, the center frequency of that circuit is comparatively low. A universal current-mode Kerwin-Huelsman-Newcomb (KHN) biquad filter has been mentioned in [22], but two VDCCs are necessary for this circuit. A current-mode universal filter has been described in [23].…”

The objective of this study is to present four new universal biquad filters, two voltage-mode multi-input-single-output (MISO), and two current-mode single-input-multi-output (SIMO). The filters employ one voltage differencing current conveyor (VDCC) as an active element and two capacitors along with two resistors as passive elements. All the five filter responses, i.e., high-pass, low-pass, band-pass, band-stop, and all-pass responses, are obtained from the same circuit topology. Moreover, the pole frequency and quality factor are independently tunable. Additionally, they do not require any double/inverted input signals for response realization. Furthermore, they enjoy low active and passive sensitivities. Various regular analyses support the design ideas. The functionality of the presented filters are tested by PSPICE simulations using TSMC 0.18 µm technology parameters with ± 0.9 V supply voltage. The circuits are also justified experimentally by creating the VDCC block using commercially available OPA860 ICs. The experimental and simulation results agree well with the theoretically predicted results.

“…Active filters play a fundamental role in analog signal processing. [1][2][3][4][5][6][7][8][9][10] They are used in various areas like communication, measurement, instrumentation, and control systems. The traditional method of implementing active filters is based on op-amps, resistors and capacitors which is not attractive anymore.…”

“…In recent years, the application of current-mode (CM) signal processing in filter design has received remarkable attention. [1][2][3][4][5][6][7][8][9][10] In CM circuits, the nodes impedances are low and the processed signals are currents which are not limited by supply voltages making this method highly suitable for low voltage design. 14 In addition, due to inherent high frequency performance and simplicity of CM signal processing, CM filters consume low power and require low chip area for a given frequency.…”

“…Profound investigations showing different kinds of filters have been designed using second generation current conveyors (CCIIs) and other current mode active building block. [1][2][3][4][5][6][7][8][9][10] Despite their numerous advantageous, most of the current conveyor-based filters suffer from a serious drawback in applications requiring voltage output. For example, Figure 1 shows two CM filters, based on CCIIs, in voltageinput voltage-output (a) and current-input voltage-output (b) configurations.…”

In this article, new voltage‐output filter realizations based on second generation voltage conveyor (VCII) as basic building block are presented. The results of this study show that VCII is a suitable candidate for applications requiring a voltage as filter output signal, considering that the availability of a low impedance voltage output terminal in VCII makes unnecessary the use of extra voltage buffers at the filter output, resulting in filter implementations with simpler structure, reduced power consumption, and chip area. New configurations of VCII based filters with first order low‐pass (LP), second order LP, and second order bandpass (BP) transfer functions are shown. The proposed circuits enjoy a very simple structure employing only one active element and four passive components. Simulation results for a VCII transistor implementation in a 0.35 μm standard CMOS technology and a supply voltage of ±1.65 V approve the presented theory.
