Re: comparator

what type/s of comparator your using?^^
verify its specification
it is like an opamp, then just like to simulate ICMR of opamp with the negative input connected to output. make sure the input stage in saturation state

Re: comparator

what i think is tools like Multisim gives you the values for a simulation model you layout/design....

jacob backer's book has explainations on how to simulate similar things
