    摘要: Various embodiments described below relate to an ESD protection device that includes a voltage controlled shunt (e.g., a transistor) to selectively shunt energy of an incoming ESD pulse away from a circuit that includes a semiconductor device to be protected. In some embodiments, the ESD protection device includes a power up detection element to determine whether the circuit has powered up. If the circuit is powered up, the power up detection element prevents inadvertent triggering of the ESD protection device.

    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.
