Hi folks,
Currently I use four identical bias ckts to generate currents for 4 different channels. To save the layout area, I can use only one bias circuit to bias 4 groups.
I cannot use simple current mirror to do this because of noise issues.
Can anyone here recommend a bias ckt?
BTW, I have a stable voltage input generated by bandgap.
Thx
