DC-TO-DC CONVERTER COMPRISING A RECONFIGURABLE CAPACITOR UNIT |
摘要 |
The present invention relates to a configurable trench multi-capacitor device comprising a trench in a semiconductor substrate. The trench has a lateral extension exceeding 10 micrometer and a trench filling includes a number of at least four electrically conductive capacitor-electrode layers. A switching unit is provided that comprises a plurality of switching elements electrically interconnected between different capacitor-electrode layers of the trench filling. A control unit is connected with the switching unit and configured to generate and provide to the switching unit respective control signals for forming a respective one of a plurality of multi-capacitor configurations using the capacitor-electrode layers of the trench filling.
