| Zusammenfassung: | A signal comparison circuit comprises a first amplifier, a second amplifier, a peak detector and a comparer, wherein the first amplifier is a zero-rising amplifier for receiving and amplifying a data signal; the second amplifier is used for receiving and amplifying a reference voltage; the peak detector is coupled with the first amplifier and the second amplifier for detecting and maintaining the maximal value of the amplified data signal and the reference voltage, and outputting the maintained data signal and the reference voltage; and the comparer is coupled with the peak detector for comparing the maintained data signal and the reference voltage and outputting the comparison result. |
