Hi,
I'm looking for advise concerning a low power voltage reference using NPN transistor as following :
Q2 is used as diode (with negative TC)
Q3 is used as zener diode (with positive TC)
This circuit create a temperature-compensated +6V reference.
So my question is what parameters of Q3 permit to obtain +6.2V ?
With the same reference, provided by different manufacturer, we found different zener voltage.
If someone have the answer of this issue (or an equation), I take it !
By advance, thank you.
BR
