Abstract
An improved one shot multivibrator circuit is described which is particularly adapted for use with field-effect transistor (FET) manufacturing techniques such as metal oxide semiconductor (MOS) large scale integration (LSI) manufacturing techniques. Such a one shot multivibrator circuit is particularly adapted for FET application because the period of its output pulse is independent of the threshold voltages of the transistors used in the circuit design. The one shot multivibrator circuit comprises a capacitor for fixing the period of the output pulse; a bias network including a current mirror as a constant current source for charging the capacitor; a first inverter stage comprising a switching transistor and a load transistor for controlling the charging and discharging of the capacitor; and a second inverter stage as the output stage for providing the output pulse having its turn-on controlled by the first inverter stage and its turn-off controlled by the voltage level on the capacitor.
