[0030] Electrostatic Discharge (Electronic Static Discharge, also known as ESD) is the uncontrolled transfer of electrostatic charge from one object to another, which can damage microchips. The purpose of the ESD protection strategy is to provide a low-resistance discharge path for a large amount of charge brought by the shock when the electrostatic shock comes. The discharge of the electrostatic charge from the lo...

Description
technical field [0001] The invention relates to the technical field of electrostatic discharge protection of integrated circuit chips, in particular to a power supply clamp electrostatic discharge protection circuit. Background technique [0002] The electrostatic protection design of the integrated circuit chip is one of the necessary conditions to ensure the reliable operation of the chip. [0003] Electrostatic shock is ubiquitous in life. With the continuous advancement of integrated circuit technology, the size of the devices that make up the circuit is getting smaller and smaller. The electrostatic shock itself has the characteristics of short time and very large instantaneous current. When the size of the device is small, the electrostatic shock will form a huge equivalent electric field inside the device, which will directly break down the device and cause the device to suffer irreversible physical damage and be paralyzed. [0004] It can be known from the related a...
