Abstract
An ESD circuit includes a first metal oxide channel device having a drain coupled to a first node, a source coupled to a second node, and a gate coupled to the first node; a second metal oxide channel device having a source coupled to the first node, a drain coupled to the second node, and a gate coupled to the second node; a first capacitor coupled between the first and second nodes proximate to the first metal oxide channel device; and a second capacitor coupled between the first and second nodes proximate to the second metal oxide channel device. The ESD circuit can further include a third capacitor coupled between the first and second nodes proximate to the first capacitor. The ESD circuit can further include a fourth capacitor coupled between the first and second nodes proximate to the second capacitor.
