The three keys method of voltage transferring characteristic is summarized in this paper.And then it is analyzed contrastively on three typical comparator.Three circuit examples are given about different comparators on fan temperature control,induction cooker overvoltage protection and BJT parameter separation.The teaching practice indicates that three stages method is helpful to the students＇ deepening their understanding of the arithmetic amplifier and the voltage comparator,so the foundation is established for the synthetic design of electronic system.
