Abstract: A capacitor for sensing a substrate voltage in an integrated circuit power device may be implemented by isolating a portion or segment of the metal layer that normally covers the heavily doped perimeter region typically used for electric field equalization. In conjunction, one or more portions of an isolation dielectric layer of silicon oxide are not removed from the surface of the semiconductor substrate, as is commonly done before depositing the metal layer. The portions of isolated silicon oxide which are not removed become the dielectric layer of the capacitor. Moreover, one plate of the capacitor is formed by the heavily doped perimeter region that is electrically connected to the substrate (e.g. a drain or collector region). The other plate is formed by the segment of metal isolated from the remaining metal layer defined directly over the heavily doped perimeter region.

Abstract: The converter uses the energy stored in the output filter of a step-down (or buck) converter and in the inductor of a step up/down (or buck-boost) converter to supply a second output of opposite sign. In particular, the converter has a first input receiving an input voltage; a first output supplying a first output voltage of a first sign; a second output supplying a second output voltage of opposite sign; a controlled switch connected between the first input and a first intermediate node; an inductor connected between the first intermediate node and the first output; a diode connected between the first intermediate node and a second intermediate node; and a dual voltage generating circuit connected between the second intermediate node and the second output.
