Hello !
I am trying to design a power amplifier, I have a initial design aproach equations but this are for BJT, I am using mosfet and my doubt is for calculate the number of fingers I found these equation M=Idc/(Jemax*Ae device) (this equation is for bjt because is using Area of emitter) my question is what will be the equivalent for mosfet to area emitter device? W*L? W*Ldrain? W*Lsource?
Thanks
Best Regards

This is for MOSFET LNA, but the equations are valid for any power MOSFET:
