Abstract
A start up circuit causes a MOS transistor to be turned on by sensing local electrical quantities thereof, specifically the potential at the drain terminal of the MOS transistor. A small current is injected into the control terminal of the MOS transistor when the potential at the drain terminal is high. For the purpose, an electric network is arranged to couple these two terminals together.
