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.
 

Check this out:

A 4-Bits Trimmed CMOS Bandgap Reference with an Improved Matching Modeling Design
Martinez Brito, J.P.; Bampi, S.; Klimach, H.
Circuits and Systems, 2007. ISCAS 2007. IEEE International Symposium on
Date: 27-30 May 2007, Pages: 1911 - 1914

You can find the paper at:

maofeng, i also downloaded the paper, it is helpful. thank you!
 
my question is, how can we design a FUSE burning circuits for bandgap trimming?
thanks!

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