Filter design with voltage conveyors

The 2004 IEEE Asia-Pacific Conference on Circuits and Systems, 2004. Proceedings., 2005
This work deals with the procedure of filter design using modern active circuit elements called voltage conveyors. Like in the case of current conveyors, various kinds of voltage conveyors can be designed and used for frequency filter synthesis. As the voltage conveyors have not been manufactured in the form of real electronic devices yet, the paper ...

A New Low-Voltage Second Generation Voltage Conveyor Using Merged Voltage Follower and DTMOS Techniques

Journal of Circuits, Systems and Computers, 2023
A very simple, compact and low-power second generation voltage conveyor circuit using only eight transistors is proposed in this work. Voltage follower stage is implemented using merged voltage follower (MVF), offering very low output impedance. A simple current mirror forms the input stage of the proposed voltage conveyor.

A new differential voltage current conveyor

2011 IEEE 19th Signal Processing and Communications Applications Conference (SIU), 2011
In this paper, a new differential voltage current conveyor (DVCCCII), which is designed by using floating gate transistors (FGMOS), is proposed. By using FGMOS transistors both the input stage of the circuit providing the arithmetic calculations is getting simpler also the linearity range is increasing due to the properties of FGMOS differential ...

Universal voltage conveyors in fractional-order filter design

2016 39th International Conference on Telecommunications and Signal Processing (TSP), 2016
In this paper voltage-mode fractional-order low- and high-pass filters using universal voltage conveyors are presented. The assumed order of the filters is (1 + α), where 0 < α < 1. The proposed structures use the continued fraction expansion approach and hence the fractional-order transfer functions of the filters are approximated by integer-order ...

Current conveyor, voltage conveyor, gyrator

Proceedings of the 44th IEEE 2001 Midwest Symposium on Circuits and Systems. MWSCAS 2001 (Cat. No.01CH37257), 2002
Interchanging the input and output stages in a current conveyor one obtains the circuit that may be called a "voltage conveyor". Using parallel connection of positive and negative voltage conveyors one obtains a gyrator that is convenient for realization of a floating inductor equivalent. A CMOS realization of this gyrator is proposed.

VOLTAGE-CONTROLLED CURRENT CONVEYORS: APPLICATIONS TO RESISTANCE-CONTROL

Journal of Circuits, Systems and Computers, 2005
Variable gain Current Conveyors have been proposed to allow control of the value on fixed resistors. In this paper, procedures will be described, taking into account the stability of different configurations when a practical CCII- is applied. Correction circuits will modify the control range. Frequency response and transients are shown.

Differential voltage current conveyor and fully differential current conveyor in standard CMOS technology for low voltage analog circuits applications

2005 12th IEEE International Conference on Electronics, Circuits and Systems, 2005
A CMOS differential voltage second generation current conveyor (DVCCII), and fully differential current conveyor (FDCCII) are presented. They have advantages of a wide bandwidth, low input impedance at X-terminal, low offset voltage at X-terminal and low voltage operation. They are useful building blocks for analog circuits, especially for applications

CMOS voltage conveyors

Proceedings of the 44th IEEE 2001 Midwest Symposium on Circuits and Systems. MWSCAS 2001 (Cat. No.01CH37257), 2002
The paper describes a concept of voltage conveyor. The voltage conveyor is obtained by interchange of input and output stages in a current conveyor. The input stage of a voltage conveyor is a current amplifier with low input impedance, the output stage is a voltage follower that has low output impedance as well.

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 ...
