Jean-Didier Legat 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: 8294492
    Abstract: An ultra-low-power transconductance device is provided, (FIG. 1b, FIG. 1c), comprising a series connection of a transistor of a first channel type (A) and a transistor of a second channel type (B), the first channel type having a different polarity than the second channel type. The transistors each have a source, a drain and a gate. The source of the transistor of the first channel type (A) is coupled with the source of the transistor of the second channel type (B) and the drain of the transistor of the first channel type (A) is coupled with the gate of the transistor of the second channel type (B).
    Type: Grant

  • Patent number: 7362140
    Abstract: The present invention provides a low swing current mode logic circuit including: a current mode logic block having data inputs and outputs; a pre-charging circuit for pre-charging the outputs; a dynamic current source; an evaluation circuit for evaluating the logic block during an evaluation phase; and, a feedback path arranged between the outputs and the dynamic current source which is responsive to a difference between the outputs. The simplicity of generating the low swing, achieved by the feedback which may be implemented by only two transistors, is in contrast with the complexity introduced by some methods used by other logic styles for achieving low swing.
