    摘要: Some embodiments relate to an electrostatic discharge (ESD) protection device to protect a circuit from an ESD event. The ESD protection device includes first and second trigger elements. Upon detecting an ESD pulse, the first trigger element provides a first trigger signal having a first pulse length. The second trigger element, upon detecting the ESD pulse, provides a second trigger signal having a second pulse length. The second pulse length is different from the first pulse length. A primary shunt shunts power of the ESD pulse away from the ESD susceptible circuit based on the first trigger signal. A current control element selectively pumps current due to the ESD pulse into a substrate of the primary shunt based on the second trigger signal.

    摘要: A gate controlled fin resistance element for use as an electrostatic discharge (ESD) protection element in an electrical circuit has a fin structure having a first connection region, a second connection region and a channel region formed between the first and second connection regions. Furthermore, the fin resistance element has a gate region formed at least over a part of the surface of the channel region. The gate region is electrically coupled to a gate control device, which gate control device controls an electrical potential applied to the gate region in such a way that the gate controlled fin resistance element has a high electrical resistance during a first operating state of the electrical circuit and a lower electrical resistance during a second operating state, which is characterized by the occurrence of an ESD event.
