Bandgap with 3bits trim, help me!!!!

[letan]

I need design a bandgap with 3bits trim, but I have not some papers discuss about this topic. Can you give me some papers?
Thanks,
Regards.

my question is, how can we design a FUSE burning circuits for bandgap trimming?
thanks!

thanks!

In my design FUSE is poly resistor, which is programmed by external voltage source.
