Secret Keeper

I am fairly new to this group, so if someone else has pointed this
out forgive me.

A question has been raised about just who performed the Fidelius
Charm, and how if Sirius wasn't the Secret Keeper how did he know
where the Potters' where? 

Is it possible, that Sirius himself is the one who performed the
Charm? In PoA, Remus said that it was Sirius, and James who did all
the brain work on how to become Animagus.

As I said, new to the group, but it was just a thought.
