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.

Click to expand...

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

maybe give out ur schematic, then it is better to talk about this.
