i want to design a fully differential comrarator that compares two differential
inputs in .13umc tech with delay less than .2ns for low resolution adc
 

Re: comparator design

Do research on the low voltage comparator design, then you will get the basic idea on the implementation.
 

Re: comparator design

thanks for the hint but i can not find good material so if have any please send me
 

comparator design

search in IEEE
 

Re: comparator design

For example, fully-differential comparator for 2.5 bit/stage pipelined adc.



You also have more simplified version without capacitors, but with different comparator structure, where threshold is determined by input diferential pair ratio.
 

Re: comparator design

can you please send me some material about the second comparator
