ABSTRACT:
Provided are an abrupt metal-insulator transition (MIT) device for bypassing super-high voltage noise to protect an electric and/or electronic system, such as, a high-voltage switch, from a super-high voltage, a high-voltage noise removing circuit for bypassing the super-high voltage noise using the abrupt MIT device, and an electric and/or electronic system including the high-voltage noise removing circuit. The abrupt MIT device includes a substrate, a first abrupt MIT structure, and a second abrupt MIT structure. The first and second abrupt MIT structures are formed on an upper surface and a lower surface, respectively, of the substrate. The high-voltage noise removing circuit includes an abrupt MIT device chain connected in parallel to the electric and/or electronic system to be protected. The abrupt MIT device chain includes at least two abrupt MIT devices serially connected to each other.
