    Thread Summary
    
                The user seeks guidance on designing a rail-to-tail CMOS OpAmp for a project. The final answer suggests using an operational transconductance amplifier (OTA) with a high output impedance current source output stage, which can swing closer to the rails than a source follower. The accompanying answer recommends the Analog Devices Educational platform for additional resources on amplifier design and output stages.

    Hello everyone,
    

    I have a question about CMOS OpAmp design. One of my Msc courses requires a project which involves design of a rail to tail OpAmp. This project should be realized both schematically and in layout. I looked for a design guide from Analog Devices, yet I couldn't find any. Is there anybody who can suggest me a good guideline to design an OpAmp?
    

    Thanks
