摘要：
This paper presents a reusable rail-to-rail operational amplifier The unity-gain bandwidth can be tuned from 75kHz to 1.5MHz with total quiescent consumption ranging from 42nA to 27.5muA with 2V supply voltage. A novel rail-to-rail architecture proposed by Duque-Carrillo et al. and a low-power low-voltage class AB output stage proposed by Silveira et al. are integrated to achieve an opamp that meets the requirements of a wide range of applications. A power optimization design methodology for a given settling time is explored and simulations results are presented.
