Patents by Inventor Giorgio Ghiozzi

Giorgio Ghiozzi 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 power amplifier which allows parallel connections
    Patent number: 6344774
    Abstract: An integrated power operational amplifier can alternatively be operated in a master or a slave mode, such that a master amplifier can be connected in parallel with one or more slave amplifiers. This arrangement allows very low impedance loads to be driven, as well as allowing the heat dissipation to be distributed over a number of operational amplifiers, thereby raising the maximum dissipation limits of integrated power systems. In addition, by eliminating the ballast resistors, more power can be delivered by the system, for the same supply voltage, and less power is dissipated.
    Type: Grant
    Filed: June 25, 2001
    Date of Patent: February 5, 2002
