Javanifard Jahanshir 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).

  • Memory circuit including booster pump for programming voltage generation
    Patent number: 6744669
    Abstract: A DC voltage boost circuit capable of improved efficiency. The DC voltage boost circuit includes an inductive element, a switching device, an output capacitive element, and a regulation circuit. The switching device periodically causes current to flow through the inductive element in response to a control signal. Each time the switching device causes current to flow through the inductive element, the inductive element stores the energy. When the switching device stops the current from flowing through the inductive element, the stored energy is then transferred to the output capacitive element. The capacitive element accumulates the packets of energy stored in the inductive element in the form of charges to form the output voltage of the booster. A regulation circuit is provided to sample the booster output voltage and to generate the control signal for the switching device such that the output voltage is regulated. The control signal can be frequency modulated or pulse width modulated.
