ABSTRACT:
A pulse timer circuit comprising a monostable multivibrator which includes two complementary transistors Q5, Q6, has the advantage of good tolerance to temperature fluctuation owing to the provision of a Schottky diode D4 connected between the emitter and base of one of the transistors Q5. The Schottky diode, D4, which has a temperature coefficient matched to that of the transistor Q5, ensures that the output pulse width from the monostable is unaffected by fluctuations in ambient temperature.
