ESD PROTECTION TECHNIQUES
摘要:
Some embodiments relate to an electrostatic discharge (ESD) protection device to protect a circuit that is electrically connected to first and second circuit nodes from an ESD event. The ESD protection device includes a first electrical path extending between the first and second circuit nodes and including first and second ESD detection elements arranged thereon. The ESD protection device also includes first and second voltage bias elements having respective inputs electrically connected to respective outputs of the first and second ESD detection elements. A second electrical path extends between the first and second circuit nodes and is in parallel with the first electrical path. The second electrical path includes a voltage controlled shunt network having at least two control terminals electrically connected to respective outputs of the first and second voltage bias elements. Other embodiments are also disclosed.
