Hello,

I have to make a 4A current source. What's the best way to do it???

Is it to put 6 mosfet in parallel with 1 ohm on ther source and one bjt with base emitter jonction across one of the resistor,

Or is it better to make this on each of the mosfets and to put all drain together?

Or other option?

Thanks
Hugues
