摘　　要：ESD是集成电路设计中最重要的可靠性问题之一。显示驱动芯片是一款复杂的So C芯片,具有多电源电压、数模混合、面积大等特点,因此ESD设计具有很大的难度。该文根据芯片的特点,分析了ESD设计难点,在基本ESD电路的基础上,以电源钳位电路和轨到轨电路组成的电源ESD保护网络为介绍重点,给出了全芯片ESD保护设计方案。Electrostatic discharge （ESD） is one of the most important reliability issues in the integrated circuit industry. Display driver chip is a complicated SoC chip, it has some special features such as multi-power, mixed-signals and large chip size, etc.. So its ESD design is very difficult. According to the characteristic of the chip, analyses for the ESD design difficulties are pro- posed in this paper. Based on the basic ESD circuits, the power ESD protection network composed of power clamp circuits and rail to rail circuits is introduced, and the whole-chip ESD protection design scheme is proposed.
