8-bit current-steering output glitches issue-help

[neter]

Dear all,

I'm design a 8-bit current-steering DAC,but,the ouput exist glitch always.

How to do reduce current cell output glitch?

Thanks a lot.

Try to add dummy mos at drain side of switch mos.

In MOS, glitch will be there. To reduce, you can go for timing analysis of the switches those are controlling the current to the out put (as current steering). If two switches are off at a time and then one is turned on, the amount of glitch will be greater. You can reduce this by timing analysis.
