low voltage Band gap reference

[shibinpv]

Hi,

I want to design to design a low supply-voltage(1.2V) BGR in 65nm technology (reference out should be around 0.6v). Can any one guide me by providing some suitable architectures and valuable suggestions.

Thanks In Advance.

There are many architectures available. I think you should first try in google.

CMOS or BiCMOS? if CMOS, this circuit is quite usual, but there is something problem with startup if match is poor...

It will start up better if you remove R1. The curvature will be more, but it is still a good reference, and it actually generates a bigger Vbe1-Vbe2 which helps with accuracy.
