The invention provides a pumping circuit with steady state voltage which employs the negative voltage pulse generated by the steady state voltage which was triggered by the static electricity discharging event and also triggered the static discharging protection apparatus. In the early stage of the said event, the differential between VDD and VSS in integrated circuit increased rapidly. When the steady state voltage of static electricity discharging is too small to trigger the discharging protection apparatus, the voltage differential between two ends of protection apparatus will be enlarged by the negative voltage pulse which is enough for the triggering. In other words, the negative voltage pulse effect advanced the said static electricity discharging protection apparatus so as to protect the integrated circuit from the damage of static electricity discharging.
