<p>PURPOSE:To obtain a one-shot pulse with an optional width and simple constitution by switching the state of a transistor(TR) at the inverting state of the input to a comparison section. CONSTITUTION:A 1st resistor 8 and a 1st capacitor 9 and a 2nd resistor 10 and a 2nd capacitor 11 are connected respectively in series with a DC power supply 6, and a connecting point VC between the 1st resistor 8 and the 1st capacitor 9 and a connecting point VR between the 2nd resistor 10 and the 2nd capacitor 11 are connected to each input of a comparator 12. Moreover, an output of the comparator 12 is connected to the DC power supply 6 via a 4th resistor 13 and connected to a base of a TR 16 via the 2nd capacitor 14 and the output of the TR is connected to the DC power supply 6 via a 5th resistor 15. Then the state of the TR 16 is switched at the inverted input state of the comparator 12. Thus, a one-shot pulse with an optional pulse width is obtained with simple constitution.</p> |
