Wien oscillators using current conveyors

Computers & Electrical Engineering, 1999
Two new Wien type oscillators using the current conveyor as the active building block are given. Both circuits have the advantage that the condition of oscillation can be adjusted by varying a single resistor without affecting the frequency of oscillation.

Analysis of CMOS current conveyor

Proceedings of the Fifteenth National Radio Science Conference. NRSC '98 (Cat. No.98EX109), 2002
Current conveyors have been used as a basic building block in a variety of electronic circuit in instrumentation and communication systems. Today they replace the conventional opamp in so many applications such as active filters, analog signal processing, and A/D, D/A converters.

Simplified BiCMOS Current Controlled Conveyor

2007 14th IEEE International Conference on Electronics, Circuits and Systems, 2007
A new implementation for simplified second generation current controlled conveyor (CCCII) is presented. The proposed circuit is very simple, it uses only two NPN transistors for signal processing, and CMOS transistors for the biasing circuit. Its electrical characteristics, voltage and current transfer, and parasitic impedance, have been evaluated.

A current-conveyor-based multiplier/divider cell

International Journal of Circuit Theory and Applications, 1996
A continuous-time multiplier/divider cell using a single current conveyor and six MOS transistors is presented. This circuit performs four-quadrant multiplication and division operations through the same topology without any additional circuitry. SPICE simulations with more accurate current conveyor models and a practical implementation of the proposed

First generation current conveyor macromodel

2010 9th International Symposium on Electronics and Telecommunications, 2010
This paper presents a macromodel of first generation current conveyor (CCI). This macromodel is suitable for fast simulations of integrated circuits containing current conveyors. The accuracy of the proposed macromodel has been verified by Spice simulations. The results show a close approximation with simulation on the transistor level but with reduced

Baseline restoration using current conveyors

1995 IEEE Nuclear Science Symposium and Medical Imaging Conference Record, 2002
This paper presents simple circuits for baseline restoration based on a commercial current conveyor (CCII01). Tests were performed, on two circuits, with periodic trapezoidal shaped pulses in order to measure the baseline restoration for several pulse rates and restorer duty cycles.

Current Conveyor Theory And Practice

1993
A current conveyor is a four (possibly five) terminal device which when arranged with other electronic elements in specific circuit configurations can perform many useful analog signal processing functions. In many ways the current conveyor simplifies circuit design in much the same manner as the conventional operational amplifier (op-amp).

Analysing networks containing current conveyors

International Journal of Electronics, 1989
The (second generation) current conveyor is a building block that can be used to design linear circuits. Current conveyors have been used to design oscillators, filters and simulated inductors. This paper presents a simple procedure for analysing circuits that contain current conveyors. The procedure is well suited for manual calculations.

Accurate CMOS-based current conveyors

IEEE Transactions on Instrumentation and Measurement, 1991
An integrable circuit technique for implementing both positive and negative second-generation current conveyors (CCII) is described. Since the proposed circuits consist of a differential pair, current sources, and current mirrors, the realization method can result in a fully integrated current conveyor.
