One-shot signal generating circuit

A one-shot signal generation circuit which generates a one-shot signal in response to change of an input signal, comprising:

• a signal transition detection section which detects transition of the input signal and generates a pulse signal;
• a timing determination section which comprises:
• a start timing determination section which detects a start edge of the pulse signal which is output from the signal transition detection section, starts a count in response to the start edge as a trigger, and generates a signal which determines the timing of a start edge of the one-shot signal based upon the count value;
• and an end timing determination section which detects an end edge of the pulse signal which is output from the signal transition detection section, starts a count in response to the end edge as a trigger, and generates a signal which determines the timing of an end edge of the one-shot signal based upon the count value;
• and
• a signal generation section which generates a one-shot signal having edges whose timing is determined by the timing determination section.
