As a beginner in OP-AMP, I just can't figure out the different stages in the given OP-AMP circuit and the working of the circuit. I have attached a picture given, the circuit diagram. Please reply asap. Thanks in advance.

Why do I get the feeling this is a homework problem?

Anyway, M1 and M2 form a differential pair, M6 is a gain stage, M8 is an output driver, and the rest of it is basically current sources.

Also M3 and M4 form a current-mirror differential to single-ended converter.
