Class-AB circuits, which are able to deal with currents several orders of magnitude larger than their quiescent current, are good candidates for low-power and high slew-rate analog design. This paper presents a novel topology of a class AB flipped voltage follower (FVF) that has better slew rate and the same power consumption as the conventional class-AB FVF buffer previously presented in liter...

During the course of screening for new antibiotics from rare actinomycetes in our laboratory, a rare actinomycete initially designated as strain A-3416 was found to produce an antibiotic with strong activity against staphylococci resistant to various antibiotics. From its unique physicochemical properties, it was judged to be a new antibiotic and named antibiotic AB-64. In this paper, taxonomic...

In this paper a new approach for design of class-AB current-mode square-root domain filters based on the electronically simulated translinear loop principle is presented. FG-MOS transistors that operate in strong inverted saturation region are employed for implementation of translinear loop circuit. The filter achieves immunity to body effect, low circuit complexity, large input dynamic ran...

An essential modification to a conventional four-stage pseudo-class AB amplifier results in a true class AB amplifier. As opposed to the conventional pseudoclass AB scheme, which uses a current mirror in the third stage, our work uses an adaptive biasing circuit in the third stage in order to drastically reduce quiescent current. The pseudo-class AB and new class AB amplifiers are designed in a...

The operational amplifier is perhaps the most useful integrated device in existence today. It is widely used in analogue computers, simulation systems and in a variety of electronic applications such as filtering, buffering and comparison of signal levels. In this paper, the different schemes of power-efficient class AB two-stage op-amps using a current replication branch and adaptive loads wer...

In this paper a novel linear transconductor topology is proposed, where class-AB behavior based on adaptive biasing exploited to improve the range. The circuit Winner-Take-All already used for OTAs, and optimized linearity, proposed features gain control input tunability. provides of 43 ?S while consuming 70 ?W. range (1% variation dc transconductance gain) 470 mVpp, about 4.5 times larger than...
