Abstract :
In this paper the design of a CMOS cascoded operational amplifier is described. Due to technology scaling the design of a former developed operational amplifier has now overcome its stability problems. A stable three stage operational amplifier is presented. A layout has been created automatically by using the ALADIN tool. With help of the extracted layout the performance data of the amplifier is simulated.
