  • Monostable multivibrator
    Patent number: 5289052
    Abstract: A monostable multivibrator which includes a differential amplifier, a non-inverted reference potential supplying device, a charging/discharging circuit, and a switching transistor, and outputs a stabilized monostable oscillating signal in response to repeated trigger signal pulses. The monostable multivibrator can properly adjust the duty ratio by controlling the value of a resistance and capacitor, and has a constant duty ratio regardless of the fluctuation of the trigger pulse.
