    摘要: A monostable multivibrator including a gate circuit, a driver circuit responsive to the gate circuit, a differentiating circuit responsive to the driver circuit and a voltage comparison circuit responsive to the differentiating circuit where the gate circuit has a trigger pulse applied to a first input thereof and the output of the voltage comparison circuit is fed back to a second input thereof, and where the gate circuit, the driver circuit and the voltage comparison circuit are each non-saturating and include a constant current source and where clipping circuitry clips the output of the driver circuit to lessen the effect of noise produced by the constant current sources on the output of the multivibrator. Further clipping circuitry may be employed to prevent saturation of the gate circuit. A common voltage source may provide bias voltages for at least the above clipping circuits and a threshold voltage for the voltage comparison circuit. In addition to a bias power supply for the gate circuit, the driver circuit, and the voltage comparison circuit, a further supply may supply a reference voltage for clipping the output of the gate circuit and for determining the asymptotic characteristic of the output from the differentiating circuit.

    摘要: A multivibrator in which a timing capacitor is connected between the collector of a first transistor and the base of a second transistor and in which a current source connected to the collector of the first transistor provides the charging current for the timing capacitor. The conduction path of a third transistor is connected between the collector and base of the first transistor and its control electrode is connected to a control voltage point for controlling the charging period of the capacitor and for ensuring oscillation when the multivibrator is connected as an astable multivibrator.

    摘要: A monostable multivibrator including a gate circuit, a time constant circuit, and an inverter circuit. An input signal to the gate circuit causes the time constant circuit which preferably includes a resistor and a capacitor to charge or discharge. A signal derived from the time constant circuit is applied to an input bias circuit including an emitter follower type transistor circuit associated with a differential amplifier within the inverter circuit to control the duration of the monostable output pulse.

    摘要: An inductance and resistance in the present monostable circuit control the duration of the quasi-stable state of the circuit. A keyed clamp damps the ringing which tends to be produced by the resonant circuit comprising the inductance and the stray capacitances coupled thereto, after the circuit switches from its quasi-stable state back to its stable state and thereby prevents false re-triggering of the circuit.The present invention relates to a monostable circuit of the type employing an inductance and a resistance as the means for controlling the duration of the quasi-stable state of the circuit.

    摘要: A regulator for a pulse generator which acts to decrease the output of the pulse generator in a linear fashion such that each pulse has an amplitude which is lower by a generally constant known amount than the pulse that immediately preceded it. By stepping down the output of the pulse generator to a critical value, the safety factor of the power source is easily determined and, if the power source loses energy in a manner which is predictable with time, the remaining useful life of the power source may also be determined.

    摘要: This monostable multivibrator includes a pair of NPN transistors arranged in the conventional manner with a capacitor connected to the collector electrode of the first transistor which conducts in the astable state, and with the capacitor and a first resistor connected to the base electrode of the second transistor which conducts in the stable state. The values of the first resistor and capacitor define the time constant that determines the time duration of operation in the astable state. The series combination of a second resistor and a third transistor which is a PNP type is connected in shunt with the first resistor, the base and collector electrodes of the third transistor being connected to the collector and base electrodes, respectively, of the second transistor. The third transistor facilitates rapid turn-on of the second transistor to terminate operation in the astable state and enables the resistance of the first resistor to be made larger than the conventional limiting value thereof that is determined by the base drive current in the second transistor and to thereby increase the time duration of the astable state.
