Hyacinth Tok 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).

  • Integrated circuit transmission lines, methods for designing integrated circuits using the same and methods to improve return loss
    Patent number: 7855614
    Abstract: Integrated circuit transmission lines are designed to match elements at opposing ends of the transmission line over a frequency range of interest. By modifying characteristics of the transmission line over the length of the transmission line, from a first end coupled to a first external element to a second end coupled to a second external element, return loss is improved. In various embodiments one or more of the width of the conductors and the distance between adjacent edges of the conductors are modified across the length of the transmission line. In an alternative embodiment, the conductors of the transmission line are segmented with each segment having a length and a width across the segment.
