TL;DR: This paper illustrates how floating-gate and quasi-floating gate MOS transistors can be efficiently employed by employing them in the design of two transconductors, which have been fabricated in a 0.5 μm CMOS process.

TL;DR: In this paper, two new versions of the flipped voltage follower are introduced, which are characterized by very low output impedance, high bandwidth speed, wide signal swing and can be easily modified for class AB operation.

TL;DR: A new CMOS transconductor is designed, which features high linearity, simplicity, and robustness against geometric and parametric mismatches and a novel tuning technique using just a MOS transistor in the triode region allows the adjustment of the transconductance in a wide range without affecting the voltage-to-current conversion core.

TL;DR: A super class-AB version of the recycling folded cascode operational transconductance amplifier (OTA) with use of an adaptive bias circuit for the input differential pair provides dynamic current boosting and increased gain-bandwidth product (GBW).

TL;DR: In this paper, a simple modification of the MOS voltage follower is introduced that provides it with efficient class-AB operation, which is achieved with the same static power dissipation, very small additional circuit complexity and lower distortion.
