Patents by Inventor Ru-Jie Wang

Ru-Jie Wang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Voltage generating apparatus
    Patent number: 8026709
    Abstract: A voltage generating apparatus including a voltage generator and a current splitter is provided. The voltage generator has an output node, and generates a first output voltage from the output node. The first output voltage rises when the temperature rises and the current flowing from the output end of the voltage generator is fixed. And the first output voltage drops when the temperature is fixed and the current flowing from the output node of the voltage generator rises. The current splitter is used for increasing the current flowing through the current splitter when the temperature rises. Therefore, the rise of the first output voltage of the voltage generator will be restrained, and the temperature compensation can be achieved.

  • Voltage generating apparatus
    Patent number: 7576599
    Abstract: A voltage generating apparatus including a current source, a first voltage source, a second voltage source, a first differential pair, a second differential pair, a voltage divider and a current mirror is provided. The voltage divider is used for reducing a voltage with a negative temperature coefficient, so as to reduce the amplification ratio of the voltage with a positive temperature coefficient used for compensating the negative temperature coefficient.
