Hi all, I am designing a circuit shown in the picture below
![??2.jpg ??2.jpg](https://www.edaboard.com/data/attachments/75/75430-27405bb1d37dca1c15560c8078e42733.jpg)
In this circuit, there have a NMOS whose name is NM0. I don't understand what's the role of it.
In fact, this circuit is a power supply and produces a 1V voltage to a DLL (delay phase lock).
How can I understand the nmos NM0? what's the role of it?
Help me please, thanx!!
And, what's the role of the capacitance?
