CMOS Voltage Differencing Transconductance Amplifier with Linearly Adjustable Transconductance Gains
2019 5th International Conference on Engineering, Applied Sciences and Technology (ICEAST), 2019In 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.

High transconductance nitride MOSHFETs
Materials Science and Engineering B, 2004Abstract AlGaN/GaN metal-oxide-semiconductor heterojunction field effect transistors (MOSHFETs) were fabricated with photo-chemical vapor deposited (photo-CVD) oxide as the insulating layer. It was found that room temperature saturation I ds , maximum g m and gate voltage swing (GVS) of the devices were 1220 mA/mm, 240 mS/mm and 4.5 V ...

A family of CMOS Operational Transconductance Amplifiers (OTA's) have been designed for very small G/sub M/'s (of the order of nA/V) in the moderate inversion region of operation using several design schemes such as current division, floating gate input stages and bulk driven techniques.

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.

High-Transconductance Ingaas/Inaias Sisfets
[1991] 49th Annual Device Research Conference Digest, 1991Summary form only given. SISFETs in the InGaAs/InAlAs lattice-matched-to-InP material system with record transconductance have been fabricated. These devices use an InGaAs channel layer grown on an InAlAs buffer layer grown on (and lattice matched to) a semi-insulating InP substrate.

Modified Gilbert transconductance multiplier
2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003A 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.

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.

Transconductance boosting of OTA
2018 International Conference on Advances in Computing, Communication Control and Networking (ICACCCN), 2018In this work, a novel method for improving the transconductance of a two-stage operational transconductance amplifier (OTA) has been presented. It is proposed to use Cascading technique to magnify the transconductance of OTA. All the circuits in work have been simulated using Cadence virtuoso and designed in 180nm technology.

GaAs MODFET transconductance stability
IEEE Transactions on Reliability, 1990The thermal stability of GaAs modulation-doped field effect transistors (MODFETs) is evaluated in order to identify failure mechanisms and validate the reliability of these devices. The transistors were exposed to thermal step-stress and characterized at ambient temperatures to indicate device reliability, especially that of the transistor ohmic ...
