The unity gain buffer will be good for designing high frequency SCF if its resistive effect can be eliminated and then the overall parasitic sensitivity will be greatly lowered.
Base on the principle of the parasitic effect and the system function, affects on the system frequency response from the parasitic effect are analyzed.
