“…The interesting features are also available in so-called fully differential current conveyor of second generation (FDCCII) presented by El-Adawy et al [9] useful for many applications [10]. A definition of the voltage differencing current conveyor (VDCC) is different [11] in comparison to [2,3,6,7,8,9,10]. This device also contains current conveyor but difference of two input voltages V p and V n is provided by internal operational transconductance amplifier (OTA) [11,12] connected to Y terminal of current conveyor forming the second stage of the circuit.…”

This paper presents a proposal and an experimental analysis of behavioral emulator of so-called z-copy controlled-gain voltage differencing current conveyor (ZC-CG-VDCC) based on commercially available devices. Most of them are electronically (by DC voltage) controllable. This work represents a suitable example of preliminary stage of development of an active device before its fabrication on silicon. This approach of development provides certain and significant information about basic functionality of the active device or the whole application and proves expected theory. The particular results of tested ZC-CG-VDCC implementation in frequency domain (transfers, gains, impedances) and DC domain (dynamics, linearity) are shown.

“…This operation corresponds to the insertion of the terms ±∞2, ∞3 and ±∞4 to the second column of (14) as shown in (22). In Figure 3a, moving the injected voltage source to the merged node of Vin1, Vin3 and Vin5 with nodes Vin2, Vin4 and Vin6 being grounded, we can obtain the filter represented by (22).…”

“…Since the differential difference current conveyor (DDCC) is a circuit similar to a DDA at the input side and a CCII at the output side [22], it enjoys the combined advantages of the CCII and DDA with high-input impedance, low-output impedance, greater design flexibility, larger signal bandwidth and wider current dynamic range, several universal filters using DDCCs have been proposed [23][24][25][26]. Unfortunately, most papers just propose their novel circuits; the design or synthesis methods for DDCC-based universal filters are not available.…”

A novel systematic approach for synthesizing DDCC-based voltage-mode biquadratic universal filters is proposed. The DDCCs are described by infinity-variables' models of nullor-mirror elements which can be used in the nodal admittance matrix expansion process. Applying the proposed method, the obtained 12 equivalent filters offer the following features: multi-input and two outputs, realization of all five standard filter functions, namely lowpass, bandpass, highpass, notch and allpass, high-input impedance, employing only grounded capacitors and resistors, orthogonal controllability between pole frequency and quality factor, and cascadable, low active and passive sensitivities. The workability of some synthesized filters is verified by HSPICE simulations to demonstrate the feasibility of the proposed method.

“…Even if different generations are described nowadays, the most often used one is the CCII and other types from it derived, e.g. electronically tunable CC [13], current controlled CC [14], differential difference CC [15], differential voltage CC [16], universal CC [17] can be mentioned as examples. The relation between the currents and voltages of a three-terminal CCII (Fig.…”

Abstract:In this paper, new minimal configuration precision fullwave rectifier is presented. The structure employs one current and one voltage conveyor and only two diodes. It enables to process both low-voltage and low-current signals. Compared to the op amp based circuit, the proposed circuit is able to rectify signals up to 500 kHz and beyond with no or small distortion. Experimental measurements are performed that show the feasibility of the new precision full-wave rectifier.
