ABSTRACT:
In an ATD circuit, a pulse width amplifier circuit is provided between a first circuit means and a second circuit means. The first circuit means generates a first output signal having a first pulse width in response to a change in external address signal and generates, when the external address signal becomes a first sawtooth signal, a second sawtooth output signal having a peak value smaller than that of the first sawtooth signal. The second circuit means receives therein the signal generated by the pulse width amplifier circuit and waveform-shapes the output signal so as to provide an ATD signal therefrom. The pulse width amplifier circuit amplifies a pulse width of the signal generated by the first circuit means. Further, the pulse width amplifier circuit generates a third output signal having a second pulse width corresponding to the first pulse width when the first output signal is received thereto and generates a fourth output signal having a third pulse width when the second output signal is received thereto.
