Dear all:
I designed a switch-capacitor comparator,which is used in the pipeline ADC.
The function of this comparator is right,.but i don't know how to simulate the offset of this comparator.
This comparator is Preamplifer+latch with autozero function.Thanks

Re: How to simulate the offset of a switch-capacitor compara

Just intentionally add idea voltage source with finite dc voltage on one of your comparator to simulate the offset of the comparator.
