Fabio Braz 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).

  • Low input impedance with amplifier
    Patent number: 6710661
    Abstract: The present invention relates to an amplifier CD including a first and a second transistor T1 and T2, connected in series between a power supply terminal VCC and ground terminal. According to the invention the transfer terminal of the first transistor T1 is connected to the bias terminal of the second transistor T2 and forms an input of the amplifier CD, the bias terminal of the first transistor T1 being connected to a reference potential terminal. An amplifier CD in accordance with the invention has low input impedance and a low common-mode output level.
