Design of a reusable rail-to-rail operational amplifier
Resumen:
This paper presents a reusable rail-to-rail operational amplifier. The unity-gain bandwidth can be tuned from 7.5 kHz to 1.5 MHz with total quiescent consumption ranging from 42 nA to 27.5 /spl mu/A with a 2 V 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 simulation results are presented.
