Device for detecting voltage fluctuation
摘要:
A device for detecting voltage fluctuation including a first amplifier for amplifying an input voltage signal, a second amplifier for amplifying the same input voltage signal with a fixed delay time relatively to the first amplifier and a voltage comparator for comparing the respective amplified output voltages to produce a high-level output at the time of increase or decrease of the input voltage signal.
