New nullor-based models are introduced to describe the behavior of the first generation current conveyor (CCI), second generation current conveyor (CCII), third generation current conveyor (CCIII), their inverting equivalents (ICCI(II)(III)), and/or their multiple output topologies (MO(I)CCI(II)(III)). These nullor equivalents include only grounded resistors to improve the formulation of equati...

To proof low voltage techniques are valid in current conveyor design, Bulk driven and composite transistor (self cascode) techniques are used to get high performance results from CCII in low voltage supply. Conventional operational amplifier circuit from literature was our choice as core of the design. Our Focus with using low voltage techniques is study the frequency characteristics of a CCII ...

Field programmable analog array (FPAA) is a rapidly growing technology for fast prototyping of analog signal processing systems facilitating the quick innovation at industry level with saving in terms of both time and cost. Analog signal processing is much faster and consumes less power than conventional digital signal processing, justifying the need for FPAA. Here we propose a Dual output curr...

Current conveyors are unity gain active elements exhibiting high linearity, wide dynamic range and high frequency performance than their voltage mode counterparts. The new current conveyor operating at low-voltage supplies high input impedance and low output impedance and consumes less power. In this study, a new low-voltage class AB second generation current conveyor (AB CCII) is presented whi...

The paper presents a current tunable multifunction filter using current conveyor. The proposed circuit can be realized as on chip tunable low pass, high pass, band pass and elliptical notch filter. The circuit employs two current conveyors, one OTA, four resistors and two grounded capacitors, ideal for integration. It has only one output terminal and the number of input terminals may be used. F...

In order to minimize the influence of electrode polarization and noise in impedance measurements, especially in the low frequency region, current injection shows several advantages compared to voltage application. Although the existence of a great variety of current sources, they meet our requirements only partially. We developed a voltage controlled current source for active front ends for a w...

This paper is concerned with the dynamic range of continuous time CMOS current mode circuits. As a representative current mode device a class AB current conveyor is examined. First, the voltage input range of the high impedance Y input is investigated. Next, the current input range of the low impedance X input is investigated. It is compared to the thermal noise in the X to Z signal path in ord...

In this paper, a circuit employing current controlled current conveyor trans-conductance amplifiers (CCCCTAs) as active element is proposed which can function both as biquad filter and oscillator. It uses two CCCCTAs and two capacitors. As a biquad filter it can realizes all the standard filtering functions (low pass, band pass, high pass, band reject and all pass) in voltage-mode and provides ...
