ABSTRACT:
A monostable multivibrator having a novel four terminal semiconductor device with a generally V-shaped emitter grounded current amplification characteristic. Means are provided to bias the operation of the device to a low point on the characteristic, to provide a trigger signal to the base of the semiconductor device for placing the device in a conducting state and, through the operation of a capacitor coupled between the gate and collector terminals, to shift the operation of the device to a high level on the emitter-grounded current amplification characteristic thereby sharply decreasing the output voltage obtained at the collector. Discharge circuit means are provided for the capacitor to gradually reduce the gate voltage and to shift the operation of the device back to the low circuit point thereby reducing the collector current and suddenly increasing the collector voltage.
