about micro power design
i would like to ask if anybody know the suitable bias circuit (with startup) for micropower design. the standard topology (for strong inversiong) used now can give current about 45 nAmp, but there's a problem with the speed and stability. the SR+ and SR- are very far from being symmetric, the worse is that the settling time is very bad (about 2 ms).
is there any way to solve this? thanks!
