Class AB CMOS tunable transconductor
2010 53rd IEEE International Midwest Symposium on Circuits and Systems, 2010A class AB tunable transconductor is presented, featuring low quiescent power consumption. Class AB operation is achieved using quasi-floating gate transistors. Highly linear tuning is obtained using resistive dividers implemented by transistors operating in triode region.

Proceedings of 40th Midwest Symposium on Circuits and Systems. Dedicated to the Memory of Professor Mac Van Valkenburg, 2002
A class AB current comparator suitable for sampled-data systems is presented. The comparator has a low and well-controlled current consumption. Because of class AB operation, a high input swing and a high dynamic range are obtained. Positive feedback has been used to reach a high speed.

Super class AB-AB bulk-driven folded cascode OTA
Integration, 2018Abstract A super class AB-AB bulk-driven folded cascode operational transconductance amplifier (OTA) with improved slew rate and unity-gain bandwidth is presented. The proposed bulk-driven amplifier utilizes the adaptively biased circuits, the bulk-driven flipped voltage follower and quasi-floating gate circuit, to implement the class-AB input stage ...

CMOS class AB single-to-differential transconductor
Proceedings of the 2005 European Conference on Circuit Theory and Design, 2005., 2006A rail-to-rail CMOS class AB transconductor, which exhibits a high drive capability and good linearity is presented. Thanks to an auxiliary feedback loop, the solution is able to convert a single-ended input into a balanced differential output. Simulations on a 0.35 /spl mu/m design powered with 2V are provided.

Guidelines for designing class-AB output stages
Proceedings of the 2005 European Conference on Circuit Theory and Design, 2005., 2006In this communication an approach for analyzing and designing low-power CMOS output stages is proposed. The analysis is carried out by taking into account output stage performance parameters which also affect main characteristics of the overall amplifier.

Class AB Micropower Operational Amplifiers
2004Class AB amplifiers contribute to minimize power in several ways: on the one hand by decoupling the large signal (i.e. slew rate and current through the load resistor), and small signal (i.e. stability) requirements on the output stage; on the other hand by reducing quiescent current consumption when the signal to be processed, as in this case the ...

Enhanced differential super class-AB OTA
2017 13th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME), 2017A fully differential Super Class AB Operational Transconductance Amplifier (OTA) is presented. To provide additional dynamic current boosting and increased gain-bandwidth product (GBW), not only adaptive biasing techniques has been applied at the differential input stage, but also Local Common Mode Feedback (LCMFB).

High PSRR Class AB Power Amplifier
2006 NORCHIP, 2006A simple class AB power amplifier topology for wide supply range is presented, which combines feedback type class AB biasing with low voltage gain boosting. The amplifier uses Miller compensation with nulling resistor, but avoids typical poor midband power supply noise attenuation of Miller compensated amplifiers by creating a cancelling signal path ...

A CMOS class AB current-multiplier
Proceedings of 1997 IEEE International Symposium on Circuits and Systems. Circuits and Systems in the Information Age ISCAS '97, 2002A technique to design four-quadrant class AB current-multiplier is described. This technique uses saturated complementary transistors and exploits the square-law behavior of MOS transistors. The particularities of this technique are high signal swing, high dynamic range, high bandwidth and low consumption. Two different approaches to design the current-
