The invention relates to a static electricity discharge protective circuit and relative technique. When there is static electric discharge accidence between the protected cushion and the earthing cushion of chip, the invention can trigger the strangulation circuit between said two cushions according to the voltage difference between said protected circuit and another power source cushion to process the static electricity discharge protection. In general, there is capacitor effect between the power source cushion and the earthing cushion as the decoupling capacitor which can protect the electricity stability, therefore, when there is the static electricity discharge accidence, the voltage on the power source cushion will not increase quickly with the voltage on the protected cushion and can supply the voltage difference to trigger the strangulation circuit. Then the invention can utilize the capacitor effect on the chip to reduce the area of static electricity discharge protective circuit. |
