Shan-Fong Hung 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 identification definition reference voltage generation circuit and boot voltage generating method thereof
    Patent number: 9075590
    Abstract: A voltage identification definition (VID) reference voltage generation circuit and a boot voltage generating method thereof are provided. In the boot voltage generating method, a VID reference voltage generation circuit is provided. The VID reference voltage generation circuit includes a preset voltage providing unit, a switch and a VID input signal detection unit. When the VID input signal detection unit detects no input of a VID signal, a control signal is generated to control the switch, such that the preset voltage providing unit provides an adjustable preset voltage.
