    Hello Hsu,

    We have produced the TI Precision Labs series and one section of the op amp training, section 7, covers "Op Amps: Common Mode Rejection and Power Supply Rejection." Viewing that session should answers your questions about the relationship between CMRR and voltage offset. You can access the training here:

    If you are a native Chinese speaker, it is my understanding that the session is available in the Mandarin language. Once you are viewing the TI Precision Labs web page select the "Global" button and it lists the different languages that may be accessed.
