Hi all,
I'm trying to design a bias source that outputs a current such that Iout * VDD is constant (within 5%). Nominal VDD is 5V.
One idea I have is comparing a scaled down version of vdd with a bandgap, and using the difference to do some (open-loop) current adjustment. Maybe some of you have some other ideas?
Thanks in advance!
