Hi Russ Kincaid

Thank you so much for your help.
May I know why Q3 and Q4 will have same drain current?
They will have same drain current only if they are connected in series right? Any equation to show the drain current is the same?
Then now they are connected in parrallel through gate, why they still have same drain current?
Kindly enlighthen me.
I may have misunderstood the circuit.
Thank you.

regards and thanks
Too
