A low-triggering circuitry for dual-direction ESD protection

摘要

A novel low-triggering, dual-direction on-chip ElectrostaticnDischarge (ESD) protection circuitry is designed to protect integratedncircuits (ICs) against ESD surges in two opposite directions. Thencompact circuit features low triggering (7.5 V), short response timen(<1 ns), symmetric deep snapback I-V characteristics, and lownon-resistance (~Ω). It passed 14 kV HEM ESD test and is very areanefficient (80 V/μm). The design was predicted by simulation that fitsnmeasurement
