Patents by Inventor Jiangmin Gu

Jiangmin Gu 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).

  • Patent number: 9337157
    Abstract: A miniature passive structure for electrostatic discharge (ESD) protection and input/output (I/O) matching for a high frequency integrated circuit is provided. The miniature passive structure includes at least one shunt stub and at least one load line. The shunt stub(s) each provide a corresponding ESD discharge path. The load line(s) are coupled to the shunt stub(s) and provide loading effects for the shunt stub(s).
    Type: Grant

    Date of Patent: May 10, 2016
    Assignee: Nanyang Technological University
    Inventors: Kai Xue Ma, Yang Lu, Jiangmin Gu, Kiat Seng Yeo
  • Patent number: 9130511
    Abstract: Designs and techniques for improving the linearity of the power amplifiers, especially of the non-linear types, operated in microwave and millimeter-wave frequency using method through purposely designed active transistors or passive devices or both, are disclosed. The techniques use the manipulation of transistors' cut-off frequencies (fT) design, attached loaded linearization stub and characteristics of space attenuation of microwave signals individually or in combination of them. The disclosed techniques provide the advantages to compromise the performance among linearity, gain and power consumption in a wide range of power amplifier types, such as Class-AB, B, C, D, E and F in the different application scenarios.
