<p>PURPOSE:To realize the analog monostable multivibrator immune to noise. CONSTITUTION:A resistor 6 is interposed between a noninverting input terminal of a comparator 2 and a delay device 1 and a transistor(TR) 4 is turned on, then an output voltage VA of the delay device 1 is divided by using the resistor 6 and an on-resistance of the TR 4 to set a voltage VB at a noninverting input terminal of the comparator 2 sufficiently lower than a falling threshold voltage VC' of an output signal 20 of the comparator 2. Since the monostable multivibrator is immune to noise around the threshold voltage, the comparator 2 with minimum malfunction is realized.</p> |
