Aragio's ESD protection solution for USB 2.0 hard macro cells provides a comprehensive defense against electrostatic discharge. This innovative design is capable of passing a 4KV ESD test using the Human Body Model (HBM), including a 5-Volt tolerant protection scheme to provide high current capability while minimizing capacitance. The library features power pads that can handle high DC currents exceeding 30 mA at 125°C. For RF, the ESD protection device library optimizes paths for ESD currents up to 6A, utilizing clamp diodes and silicon-controlled rectifiers to deliver robust protection with reduced capacitance. The RF ESD protection is characterized to minimize input resistance drops through metal interconnects, ensuring reliable chip-level ESD analysis.
