Input offset simulation

1. Your comparator has gain stage and latch stage.
2. You can not see DC offset at latch stage, because it is saturated at VDD or GND.
3. Set your clock high to let the latch stage in driving mode. (clk=H, driving mode; clk=L, latch mode)
4. You do AC simulationto get voltage gain of your gain stage output.
5. You do DC simulation and do Monte-Carlo simulation. Short gain stage input to let zero input offset. Check gain stage output DC offset voltage for 3 sigma.
6. (output offset)/(voltage gain)=(input offset)
7. You do not worry "how about the offset of latch stage?". Your gain stage offset dominates total offset, because your gain stage voltage gain >20.

very good
