Hi team,

What state does the PSRR in Figure 5-15 represent?
The average value is 100 dB, but in this figure it is around -120 dB.
Also, please explain why PSRR is listed as negative only in this figure.

Best Regards,
Ryu.

Per your question, I have recently replied to the similar question over the E2E. Please see the thread below.

If this is not clear, please let me know. I am going to close the query for now. You can still post comments if my previous reply did not answer your question.

Best,

Raymond
