ABSTRACT:
A semiconductor device includes a first detection circuit, a second detection circuit, a determination circuit and a pulse generation circuit. The first detection circuit detects the leading edge of the pulse waveform of an input signal. The second detection circuit detects the trailing edge of the pulse waveform of the input signal. The determination circuit determines whether the pulse width of the pulse waveform is shorter than a given period, based on detection results of the first detection circuit and the second detection circuit. The pulse generation circuit generates a pulse signal when the determination circuit determines that the pulse width of the pulse waveform is shorter than the given period.
