Sridevi R. Joshi 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).

  • Switchable power domains for 1.2v and 3.3v pad voltages
    Patent number: 7098692
    Abstract: An integrated circuit includes a core circuit and a buffer circuit. The buffer circuit includes a plurality of input buffers and a plurality of output buffers that service a plurality of voltage domains on a single set of input/output lines. These voltage domains are controllable to service multiple voltage levels, consistent with various interface standards. In one construction, the core circuit operates at 1.2 volts and the buffer circuit supports both a 1.2 volts interface standard and a 3.3 volts interface standard.
    Type: Grant
    Filed: March 11, 2005
    Date of Patent: August 29, 2006
    Assignee: Broadcom Corporation
    Inventors: Sridevi R. Joshi, Guangming Yin, Mohammad Nejad, Daniel Schoch
