I'm happy if anybody can help me.
I designde a circuit ,when i get the chip ,I find my bias have problem.
So I need a 10ua current source to setup the circut.
How can i get the cuurent,use res,cap........
do you need to sink or source the current? In the first case connect an appropriate variable resistor to your positive supply and through a current meter into your pin. Adjust the variable resistor until you get 10uA.
In the second case, connect the variable resistor to your negative supply and do as above.
I hope it helps!
