Patents by Inventor Martha Chan

Martha Chan 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).

  • CMOS logic gate clamping circuit
    Patent number: 5442304
    Abstract: A gate clamping circuit is disclosed that includes a logic gate and a bias circuit arrangement. Through this clamping circuit the speed of operation of the circuit during both low to high and high-to-low transitions of the output signal are optimized while power consumption is minimized.

  • High-speed sense amplifier with regulated feedback
    Patent number: 5418482
    Abstract: A sense amplifier is provided that has improved speed from input to output, particularly during low-to-high transitions on the output and minimizes power consumption. By removing the product term window circuit from the critical node, the overall speed of the amplifier is maximized. In addition, circuitry is included to speed up low-to-high transitions, high-to-low transitions and provide increased noise immunity over temperature variations.
