Current source is modified into a current conveyor

IEEE Circuits and Devices Magazine, 1997
The author shows theoretically using a matrix representation of the small-signal response that a bipolar transistor circuit usually used as a current source can be modified to form a second-generation current conveyor. This element is useful in synthesis of active filters and high-speed amplifiers.

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.

The implementation and applications of current conveyors

Microelectronics Journal, 1989
Abstract The realization of current conveyors using op amps has been discussed, implemented and experimentally verified so that they can be integrated on a single chip. Nowadays, an important criterion of success for a circuit is that it should be easily integrable. Contemporary circuits have been tested and the best one is analysed theoretically and

Integrated Current Conveyor

1993
This chapter has presented a new integrable current conveyor topology which offers the promise of improved accuracy, wider frequency bandwidth, smoother transient response, and higher output impedance. This expectation has been confirmed by the performance of the PA630/PA630A ICs, which incorporate this topology and are fabricated on a complementary ...

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).

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

Current conveyor based electrometer

AEU - International Journal of Electronics and Communications, 2005
Abstract A current conveyor based electrometer is designed to improve the frequency response of the electrometer. The input current is current amplified by a current conveyor. Current conveyor is realized by operational amplifier/resistor configuration.

CMOS Implementations of Current Conveyors

2014
In order to make CC-based circuits compatible with CMOS digital circuits, a lot of attention has been given in the literature over the past two decades to evolve CMOS-based Current Conveyors. In this chapter, we bring out some of the important developments in this area.

Low-voltage current controlled current conveyor

Analog Integrated Circuits and Signal Processing, 2009
A novel second-generation Current Controlled Current Conveyor (CCCII) topology is introduced in this paper. Compared with the corresponding already introduced topologies, the proposed CCCII offers the advantage of low-voltage operation capability. In addition, due to the absence of PNP or PMOS transistors for handling ac signals, its performance in ...

Designs for a wideband current amplifier and a current conveyor

IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1994
Designs for a current amplifier and a current conveyor, both based on the first generation current conveyor, are discussed. Circuit details are given and simulation results shown. The results indicate that the current amplifier can achieve a 200 MHz bandwidth, and the CCI a 90 MHz bandwidth, in standard bipolar technologies. >
