ESD protection circuit for 8.5Gbps I/Os in 90nm CMOS technology

摘要

In this paper we designed an ESD protected CML driver for 8.5Gbps data rate. ESD protection for this circuit is provided with DSCR. A detailed analysis is done on the impact of ESD protection on performance of the driver. It is shown that DSCR offers up to 2.7kV HBM protection with very small impact on performance of the driver.
