Hi to all,
Is there a way to generate a precise reference voltage starting from a stable external power supply (eg +3 / -3V from +2.5 / -2.5v)?
I should do this in an IC (I'm simulating with Tanner EDA and a 0.25um layout).
I heard about the "charge pumps", could I use one?But I do not know how they work and even what are the design criteria.
Can you help me?
