Abstract :
The design of an integrated CMOS cascoded operational amplifier with two differential input stages is described. By using the nested Miller compensation the stability of the operational amplifier is ensured. The layout has been created automatically by using the ALADIN tool and prototype circuits have been fabricated. The small signal model for the amplifier is depicted and the test results are presented.
