Zusammenfassung:	An adaptive duo-gate MOSFET includes a trench MOSFET and an adaptive element. The trench MOSFET includes a source, a drain, a first gate, a second gate, and a dielectric layer between the first and second gates. Herein, the first gate may generate charge-coupling in blocking operation, and the second gate may form channel in the trench MOSFET when in conduction operation. The adaptive element is electrically coupled to the first gate, the second gate, and the source respectively. When a potential difference between the second gate and the source is larger than a predetermined value, the first gate and the source are electrically disconnected and then the first gate and the second gate are electrically connected. After a predetermined time, the first gate and the second gate are electrically disconnected and then the first gate and the source are electrically connected.
