Abstract:
1. A DIAC-like structure comprising a first n+ region and a first p+ region formed in an R-well to define a first contact region, a second n+ region and a second p+ region spaced laterally from the first contact region, at least a first MOS device formed between the first and second contact regions, wherein the first MOS device is defined by a first gate formed over a first channel region between the first n+ region and a floating n+ region, a second MOS device defined by a second gate formed over a second channel region between the floating n+ region and the second n+ region, wherein the first n+ region and first p+ region are connected to a high voltage node or pad, and the second n+ region and second p+ region are connected to a low voltage node, additional MOS devices between a first contact region as defined by the first n+ region and the first p+ region, and a second contact region as defined by the second n+ region and the second p+ region, each MOS device including a gate, wherein the gates of the MOS devices are individually biased, wherein alternate gates are connected to the high voltage node, while the other gates are connected to the low voltage node.
