高速IO接口的ESD保护 APN001 ESD Protection for High Speed I/O Data Lines Abstract These days, our modern society has rapidly come to fully depend on electronics. And modern computers are based increasingly on low power logic chips, all with ESD sensitivity due to MOS dielectric breakdowns and bipolar reverse junction current limits. The ICs that control I/O ports (USB, Ethernet, etc.) are not an exception since the majority of them are designed and manufactured based on CMOS processes which make them extremely sensitive to damage from ESD conditions. Because the majority of I/O ports are hot insertion and removal systems, they are extremely vulnerable to receive ESD conditions possibly generated by the users or……
