<p>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.</p> |
