Title: Laser Fuse
Post by butcher_tekkotsu on Oct 19^th, 2005, 2:32am

Hello,
:)
I'm wondering how to design laser fuse. ???
My circuit has 2 bits of logic trimming to adjust biasing current.
00
01
10
11

I would like to change this logic value using laser fuse.
Does someone know good idea?
I would not like to use pull-up or pull-down resistor ,because some currrent flows from Vdd to GND.
