This is my understanding.

In the attached picture, the maximum current that can flow is 1A. The higher Vgs, the higher the POSSIBLE current (if the load were smaller for example). Therefore, if I have a high Vgs, then the current through the mosfets will vary as a function of my input voltage which is NOT what I want??

I know I need the resistance across the mosfets to be as small as possible to minimize conduction losses, it's just confusing where exactly that happens. I thought the Rdson is the smallest, the mosfet is fully on, in the saturated (active) region.

However, this makes less and less sense to me as time goes on. If someone could give any definitive answer as to how the mosfets in my example should be biased to give the lowest conduction loss.

Thanks for any help.
