Current-jump-control circuit including abrupt metal-insulator phase transition device

摘要

A current-jump-control circuit including an abrupt metal-insulator phase transition device is proposed, and includes a source (100), the abrupt metal-insulator phase transition device (200) and a resistive element (300). The abrupt metal-insulator phase transition device includes first and second electrodes (230,240) connected to the source, and shows an abrupt metal-insulator phase transition characteristic of a current jump when an electric field is applied between the first electrode and the second electrode. The resistive element is connected between the source and the abrupt metal-insulator phase transition device to control a jump current flowing through the abrupt metal-insulator phase transition device. According to the above current control circuit, the abrupt metal-insulator phase transition device can be prevented from being failed due to a large amount of current and thus the current-jump-control circuit can be applied in various application fields.
