Abstract
A pulse generating circuit generates a pulse with a desired pulse width even when a process parameter for manufacturing fluctuates or a source voltage varies. The pulse generating circuit includes a first voltage outputting section having a first delay circuit and operating to output a first voltage changing from a high level towards a low level based on a first time constant according to a one-shot pulse, a second voltage outputting section having a second delay circuit and operating to output a second voltage changing from a low level towards a high level based on a second time constant according to the one-shot pulse, and a differential circuit to generate a pulse with a pulse width corresponding to a period from a time point of inputting the one-shot pulse to a cross time point when the first voltage coincides with the second voltage.
