Filed: 1988-05-23
Abstract: PURPOSE:To make a transient phenomenon against a power voltage stable and to obtain a prescribed pulse width by giving a constant current to a resistance part in a pulse generating circuit utilizing the transient phenomenon in case of discharging a capacitor. CONSTITUTION:The width of a pulse outputted from an inverter 12 of the next stage independently of the fluctuation of a power voltage is made stably by giving a constant current from a capacitor 11. For example, in case of using a depletion MOSFET 3, the capacitor is discharged at a prescribed time constant continually without being affected by the power voltage as a constant current. Thus, the generated pulse always has a constant width. In case of connecting a MOSFET 7 in parallel with a depletion MOSFET 6, an output of an inverter 5 is given to a gate of the MOSFET 7 and the depletion MOSFET discharges a current continually at a prescribed time constant, then a current always flows to the MOSFET 7. Thus, the width of the pulse outputted from the inverter 5 is always constant.
