Chee Quang Quek 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).

  • Method and apparatus for integrating power amplifiers with phase locked loop in a single chip transceiver
    Patent number: 8565698
    Abstract: A phase locked loop and power amplifier are integrated on a single chip. To eliminate cross-talk between the components, a frequency translation block is introduced to change the output frequency of the PLL. To isolate the components from unwanted feedback, a high isolation buffer is introduced between the components. To further isolate the components, the voltage supply domains for each component are physically separated. Each separate voltage supply domain can include a separate high isolation ring, separate voltage regulator, and separate bandgap reference.
