Abstract: A method for detecting a variation of input voltage. The method is generating an indication signal based on the input voltage, and comparing the input voltage with a first reference signal. The first reference signal is smaller than the indication signal, and if the input voltage is consistently smaller than the first reference signal during a first time duration from the moment when the input voltage is decreased to the first reference signal, the indication signal is decreased after the first time duration.
