Hi all,
I was working on a bandgap reference circuit and I wanted to know if the Vbg versus temperature curve,
i.e. the bow shaped curve has to have a centre point (flattest part of the curve) at 27 degree celsius, for Vbg=1.26V.
I was trying to simulate my circuit and I see that my curve is flat at the leftmost extreme rather
than being flat at the centre.
Any thoughts on why this is happening ?
