Abstract
The present invention relates to a pulse signal generation circuit for changing a pulse width of an input pulse signal and outputting an output pulse signal having the changed pulse width. In an aspect, the pulse signal generation circuit may include a control signal generator configured to generate at least one control signal according to a pulse width of a input pulse signal and a pulse signal generator configured to control a pulse width of an input pulse signal in response to a control signal and to generate an output pulse signal with the controlled pulse width. The control signal controls the pulse width of the output pulse signal.
