Problems solved by technology

[0014] However, since the ground pin 212 is connected to the electrostatic discharge ground wire ESDVSS1, the noise jitter in the digital domain will be transferred to the analog domain, thereby reducing the normal working performance of the analog domain, such as the signal-to-noise ratio and other indicators

Abstract

The invention provides a chip provided with a high electrostatic discharge performance, which comprises a numerical field and a plurality of simulation fields, wherein the numerical field comprises a grounding pin, a power pin, a signal pin and an electrostatic protection circuit; each simulation circuit comprises a grounding pin, a power pin, a signal pin and an electrostatic protection circuit; the electrostatic protection circuit in the numerical field comprises an electrostatic discharge power wire connected with the power pin, and an electrostatic discharge ground wire connected with the grounding pin in the field; and the electrostatic protection circuit in each numerical field comprises an electrostatic discharge ground wire and an electrostatic discharge power wire connected with power pin in the field. Electrostatic discharge ground wires in two adjacent fields are connected together, an electrostatic discharge grounding terminal is led out of each electrostatic discharge ground wire, and the electrostatic discharge grounding terminals are connected with the grounding pin in the numerical field through wires. Therefore, a passage with higher electrostatic discharge capacity is additionally established.

Description

【Technical Field】 [0001] The present invention relates to the field of ESD design, in particular to a chip with high ESD performance. 【Background technique】 [0002] ESD (Electro-Static discharge) means "electrostatic discharge". Static electricity is an objective natural phenomenon, which is unevenly distributed on the chip itself, on the human body, on the machine, and on the environment where the chip can exist and the things around it. These static charges may be released in some way at any time. The characteristics of electrostatic discharge are high voltage, low power, small current and short action time. It is very important to improve the ability of integrated circuits (ICs, also called chips) to protect against electrostatic discharge. [0003] The purpose of the electrostatic protection in the chip is to prevent the working circuit of the chip from becoming an electrostatic discharge path and be damaged, and to ensure that the electrostatic discharge occurring between ...
