Abstract
A pulse signal generator includes a first delay device for delaying an input pulse signal and converting the input signal into a first intermediate signal. A power supply voltage detector detects a power supply voltage and outputs a signal representative thereof. A second delay device serves to delay the first intermediate signal and to convert the first intermediate signal into a second intermediate signal in response to the output signal from the power supply voltage detector. A logic OR operation is executed between the first and second intermediate signals, and an output signal is generated in response to the first and second intermediate signals. The output signal has a pulse width, which is greater than a pulse width of the input signal when the power supply voltage lies in a predetermined range.
