hello
i need a supply independent current reference circuit.
Vdd range 1.3-3.3V Iref=2uA
I have found this ciuruit in Maloberti's book. The thing is it is not accurate in the corners . What can you advice me? Of course the startup circuit will be added.
What resistor will be most stable over temperature? I'm using AMS 0.35um
Maybe you can suggest another circuit?
regards
