Operational Transconductance Amplifier-Based Nonlinear Function Syntheses [PDF]
IEEE Journal of Solid-State Circuits, 1989 It is shown that the operational transconductance amplifier, as the active element in basic building blocks, can be efficiently used for programmable nonlinear continuous-time function synthesis. Two efficient nonlinear function synthesis approaches are presented.

Transconductance Enhancement Method for Operational Transconductance Amplifiers
Electronics Letters, 2010 An improved recycling structure for an operational transconductance amplifier is proposed. The proposed structure separates the AC path from the DC path, and achieves a significant boost in transconductance under the same power and area budget. A folded-cascode amplifier employing the improved recycling structure was implemented in SMIC standard 0.13 ...

Transconductance Cancellation for Operational Amplifiers
IEEE Journal of Solid-State Circuits, 1977A low-cost internally compensated integrated-circuit operational amplifier occupying a small die area can be fabricated if the compensation capacitor value is low. This objective is attained when the amplifier-input-stage transconductance is reduced to a minimum provided the frequency response remains unchanged.

The Research of Operational Transconductance Amplifier
2011 International Conference on Control, Automation and Systems Engineering (CASE), 2011A topology structure of operational transconductance amplifier is proposed to be devised in this paper. In order to make it have the feature of high-speed, large bandwidth, and high stability, a two-stage cascode structure amplifier is designed by using cascaded single-stage amplifier.

Designing operational transconductance amplifiers for low voltage operation
1993 IEEE International Symposium on Circuits and Systems, 2002To design operational transconductance amplifiers (OTAs) for high-performance applications it is necessary to use cascoded current mirrors. In low-voltage applications the standard cascoded current mirror cannot be used. The solution is to use the generalized high-swing cascoded current mirror.

Operational Transconductance Amplifiers (OTAs)
2014This chapter describes operational transconductance amplifiers (OTAs) and their linearization for use in g m -C filters. Super-source-follower and digitally programmable OTAs are detailed. The common-mode feedback used in these OTAs and a buffer amplifier are described. A OTA implemented in 120 nm CMOS is introduced inclusive measured results.

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.
