RF ESD cells in TSMC 55nm LP targetting low-capacitance ESD protection.
This library is a production-quality, silicon-proven ESD library in TSMC 55nm. The library does not have general ESD architecture as it is not a full I/O, but rather is a collection of standalone ESD cells that target low-capacitance RF ESD protection. The library’s ESD targets are consistent with ANSI, JEDEC and ESDA standards. The library includes a wide- variety of low-capacitance RF and analog ESD. There have operating ranges from 0 to 5V protection and support a wide range of high-performance interfaces including HDMI, LVDS, USB and wireless front-ends. Also included is a range of IEC 61000-4-2 system-level ESD protection that supports digital and analog I/O cells.
