Supply independent current?

[iloveics]

I have a basic understanding of current mirrors, but this circuit is very confusing to me. How would I solve for the current passing through R? Is the voltage at the top of R greater than 0??

YES

It seems that you connect the MOS-FET inversed! Are they N-MOS?

 

[Santoshalagawadi]

yes the current is greater than zero

Mosfet are a active load

BJT are the current, but the right one has a less current than the other one.

I = N(Vbe/R)
