摘要： An oscillation detector includes an amplitude variation detection circuit configured to generate a first pulse signal by comparing levels of voltages with each other, a frequency variation detection circuit configured to generate a second pulse signal by filtering the first pulse signal and allowing to pass a frequency component that is less than or equal to a certain frequency among frequency components of the first pulse signal, and a time variation detection circuit configured to output an oscillation detection signal when the second pulse signal has consecutive pulses for a period of time.
