Inhalt:
A novel CMOS operational amplifier with two differential stages has been fabricated and has been measured successfully. A nested Miller compensation is used to ensure a stable operation. The layout has been created automatically by using the ALADIN tool. An appropriate smallsignal model is depicted for the amplifier and the measurement results are presented.
