Design and analysis of high Transconductance Current Follower Transconductance Amplifier (CFTA) and its applications

Analog Integrated Circuits and Signal Processing, 2017
A high transconductance Current Follower Transconductance Amplifier (CFTA) is proposed in this paper. The proposed CFTA consists of current follower and transconductance stage with NMOS cross-coupling to enhance the transconductance. The NMOS cross coupling stage forms negative transconductance which results in higher transconductance and wider tuning ...

Transconductance amplifier structures with very small transconductances: a comparative design approach

IEEE Journal of Solid-State Circuits, 2002
A family of CMOS operational transconductance amplifiers (OTAs) has been designed for very small G/sub m/'s (of the order of nanoamperes per volt) with transistors operating in moderate inversion. Several OTA design schemes such as conventional, using current division, floating-gate, and bulk-driven techniques are discussed.

A linear operational transconductance amplifier with automatic offset cancellation and transconductance calibration

ICECS'99. Proceedings of ICECS '99. 6th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.99EX357), 2003
Operational Transconductance Amplifiers (OTA's) with linear input-output characteristics have become the focus of attention as a fundamental building block for analogue time-continuous circuits. Especially they are used in filters and instrumentation amplifiers with high cutoff- or corner frequencies.

Modified Gilbert transconductance multiplier

2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003
A novel multiplier is proposed. The design is based on a Gilbert multiplier with a negative resistance input transconductance stage. By replacing the emitter degenerated long-tail pair of Gilbert multiplier, the 'gain constant', linearity and gain accuracy are improved.

Transconductance Filter Synthesis with NAM

2016 IEEE Intl Conference on Computational Science and Engineering (CSE) and IEEE Intl Conference on Embedded and Ubiquitous Computing (EUC) and 15th Intl Symposium on Distributed Computing and Applications for Business Engineering (DCABES), 2016
A systematic synthesis method to generate transconductance filters using nodal admittance matrix (NAM) expansion is proposed. The obtained circuits with two input voltage terminals and three output currents employing only two grounded capacitors and three resistors can be used to realize the transconductance-mode universal filter.

Optically controlled transconductance amplifier

Proceedings of the International Conference & Workshop on Emerging Trends in Technology - ICWET '11, 2011
This paper presents Y parameter analysis for optically gated MOSFET at RF frequency. Simulation is done using MATLAB and analysis for Y parameter is done under dark and illuminated condition for varying optical power. It has been seen that device transconductance is highly influenced by optical illumination even for small optical power. Optical effects

CMOS Voltage Differencing Transconductance Amplifier with Linearly Adjustable Transconductance Gains

2019 5th International Conference on Engineering, Applied Sciences and Technology (ICEAST), 2019
In this work, a circuit configuration for the realization the CMOS voltage differencing transconductance amplifier (VDTA) with linear tunable transconductance and wide-input dynamic range is introduced. The circuit design technique is achieved by squaring the long-tail bias current of the differential-input voltage-to-current converter circuit.

CMOS transconductance element

Proceedings of the IEEE, 1986
A cross-coupled, ratioed quad cell was described by Nedungad, and Viswanathan [1]. One useful property of the quad is that it enables a linear large-signal transconductance cell. The other property that can be exploited is that it gives an output current proportional to the square of a differential input signal.
