PURPOSE:To stabilize a pulse width and to make the pulse width variable by comparing a waveform, which is obtained with resistance-dividing an input pulse by means of a comparator, with the waveform delayed by means of a resistance and a capacitor, and generating a sampling pulse. CONSTITUTION:A sampling pulse generating circuit consists of a comparator 6, resistances 4 and 5 to voltage-divide the input pulse, a resistance 2 to delay the input pulse, and a capacitor 3. In such a way, by subtrating the voltage- divided waveform of the input pulse and the delayed waveform by means of the comparator 6, the sampling pulse is generated. Thus, the stable sampling pulse, which has the stable pulse width and can easily make the pulse width variable, can be generated. |
