回复 2# feynmancgz
Thank you for the questions.The comparator is used to detect the two inputs' zero crossing point,which means the two inputs change their conditions that one is bigger than the other one to the opposite.The design is under 180nm technology ,which is longer than the original design.
The bandwidth is about 200M,with a load of 1pF capacitor.
In my application ,clock-controlled comparators can't be used ,which means dynamic comparator is not suitable.
You mentioned that pream+latch may be a good idea ,but does it work without a preset? |
