    Help me design a fully differential comparator design

    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

    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.
