  • Balanced amplifier and filter using the same
    Patent number: 6919768
    Abstract: A balanced amplifier comprising a pair of voltage-to-current converters including a first input terminal, a second input terminal, a first output terminal and a second output terminal to convert an input voltage applied to the first input terminal into an output current output from each of the first output terminal and the second output terminal, the second input terminal and the second output terminal of one of the converters being connected to the second input terminal and the second output terminal of the other of the converters to cancel common-mode components each other and extract differential-mode components.
    Type: Grant
    Filed: March 2, 2004
    Date of Patent: July 19, 2005
    Assignee: Kabushiki Kaisha Toshiba
    Inventors: Takeshi Ueno, Tetsuro Itakura, Krystyma Czarnul, Zdzislaw Czarnul
