摘要
Dual diodes with embedded silicon controlled rectifier (DD-SCR) for high-speed applications are presented. A new DD-SCR topography is shown to exhibit a high failure current (42), small on-state resistance (RoN), low voltage overshoot and low parasitic capacitance. This is a preferred device option for broadband high-speed data converter applications in advanced 28 nm CMOS processes. A comprehensive device characterization demonstrates the design tradeoffs and the superior ESD performance in relation to the devices' variations capacitance in the sub 40 fF range.
