    摘要: The present invention provides a high-side driver circuit including a power transistor, the first transistor, the second transistor, the second capacitor, the second diode, a start-up circuit. The start-up circuit is coupled between a resistor and the second capacitor to complete a gate driving circuit. And, the aforementioned resistor can either be the gate resistance of the power transistor or an external resistor. The design of start-up circuit enables the functionality of the bootstrap capacitor of being charged to a designate voltage level. Thus, the depletion-mode transistor can be controlled to turn on/off without a floating voltage source or a negative voltage source.

    摘要: The present invention provides a current limit circuit apparatus, coupled with the gate of a GaN transistor. The current limit circuit comprises a diode, a first transistor, a second transistor, a first resistor, a second resistor, a third resistor and a fourth resistor. The source and the drain of the first transistor couple with the diode. The source of the second transistor couples with the gate of the first transistor. The source of the first transistor couples with the first transistor. The source of the second transistor couples with the second resistor. The third resistor couples with the fourth resistor and the gate of the first transistor. The first transistor turned off and the gate current is limited. When the current of the gate of the GaN transistor exceeds the predetermined value, the breakdown voltage is increased by limiting the gate current.

    摘要: Whenever a user prepares to use an application, or a file, to treat the scanned image of an object, the user only needs to place the object on a scanner and to select the icon of the application, or the file, and compile it with the icon of the scanner. The utilization of the present invention will automatically drive the driver of the scanner and integrate the relative information into the driver. Thus, after the scanned image is acquired, the application, or relative application of the file, is automatically active to treat the scanned image. Further, the format of the scanned image could be transformed by some applications such as the OCR.
