The objective of “A Three?Stage Comparator and Its Modified Version With Fast Speed and Low Kickback” is to present an improved CMOS comparator architecture that enhances comparison speed and reduces kickback noise by adding an extra amplification stage and using a CMOS input pair in the modified design to cancel noise and increase drive efficiency compared to conventional two?stage comparators, achieving better performance for high?speed analog?to?digital conversion applications while maintaining low input?referred offset and noise.
