摘要
时钟频率的增加,使得芯片设计中的电感效应已经不能忽视。通过分析传输总线上的同步开关噪声(SSN)产生的机理,提出对总线输入/输出信号编解码,达到减少线间电感SSN的目的。并且将此方法用于解决一款OLED驱动芯片存在的SSN问题。
Inductance effects couldn＇t be neglected in circuits with increasing of clock frequency. In this paper, it analyzes the theory related to simultaneous switch noise, describes a new method to reduce inductance to get low simultaneous switch noise by coding, and uses this method to solve an SSN problem of an OLED driving chip.
