Hi,
I'm designing a VDD/2 reference that splits a 1.5V supply. Error needs to be ~1mV or less, and the generator needs to be low impendance.
One way to do it: I could use a simple resistor divider, but I need switches in series with the divider to turn it off when not in use... These switches will contribute a Resistance->Voltage error... Does anyone know of any schemes to try and cancel the error contribution from the switches?
If anyone can think of any other good schemes, lemme know.
Thanks!
