Class AB amplifier with enhanced slew rate and GBW. International Journal of Circuit Theory and Applications. 2019; 47(8): 1199- 1210. https://doi.org/10.1002/cta.26501097-007Xhttps://academica-e.unavarra.es/handle/2454/41928The design of a micropower class AB operational transconductance amplifier with large dynamic current to quiescent current ratio is addressed. It is based on a compact and power-efficient adaptive biasing circuit and a class AB current follower using the Quasi-Floating Gate (QFG) technique. The amplifier has been designed and fabricated in a 0.5 um CMOS process. Simulation and measurement results show a slew rate (SR) improvement factor versus the class A version larger than 4 for the same supply voltage and bias currents, as well as enhanced small-signal performance.17 p.application/pdfeng© 2019 John Wiley & Sons, Ltd.Current followersCurrent amplifiersAnalog integrated circuitsCMOS integrated circuitsClass AB circuitsinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
