Re: Curvature-Compensated BiCMOS Bandgap with 1-V Supply Vol
Hi amriths04 and thanks for you answer.
Do you know that paper? Have you read it?
I'm trying to design that circuit, following the equations described but it seems no possible to reach a performance below 10ppm/^C.
I'm using a 0.35 CMOS tech, not a BiCMOS, but other papers describe about the same circuit reaching about the same performances (about 7 ppm/^C).
Moreover, starting from the simplest 1st order compensated circuit descibed in fig 1 it is hard to reach 20ppm/^C.
If you have already done this kind of design what's for example your values for the current in the BJTs and the resistances?
TIA,
CBs.
