  • Patent number: 7411440
    Abstract: An embodiment of this invention provides a circuit and method for reducing the number of electronic components needed to calibrate circuits on an IC. A multiplexer is located on the IC where the outputs of a plurality of circuits located on the IC are each connected to a separate data input of the multiplexer.

  • Patent number: 6995583
    Abstract: A method and structure for control of a rise time of a bus signal coupled to a driver circuit. A bus is coupled to the driver circuit and is operable to carry the bus signal. Voltage control elements are coupled to the driver circuit and the bus, and are operable to increase or decrease a voltage of the bus signal relative to a ground at one or more time instants. A control circuit coupled to the voltage control elements is operable to control the switching of the voltage control elements, thereby controlling the voltage level of the bus signal. Controlling a rise time of the bus signal of the driver circuit includes adaptively adjusting a voltage level of the bus signal relative to a ground at one or more discrete times by the use of the voltage control elements.

  • Patent number: 6906567
    Abstract: A method and structure for providing dynamic control of a slew rate of an electronic circuit. The structure has a signal line that is coupled to a number of capacitive elements that may be selectively switched in or out of the electronic circuit in order to provide precise control of the slew rate of the electronic circuit. A control element switches the capacitive elements into the signal line so that the slew rate may be precisely controlled at one or more time instants. The method includes determining a desired slew rate of the electronic circuit. Based upon the desired value of the slew rate, one or more of the capacitive elements are switched into the signal line at one or more time instants without changing an output impedance of the electronic circuit.

  • Patent number: 6795055
    Abstract: Devices, systems and methods for facilitating positioning of a cursor on a display device are provided. For example, an input device is provided which includes a shifter configured to electrically communicate with a computer. The shifter is configured to enable functional information, provided by a mouse-type input device, to provide selected functionality of the cursor. The shifter provides a shift-disable mode and a shift-enable mode so that, while in the shift-disable mode, the shifter enables the mouse-type input device to influence movement of the cursor on the display device. For instance, a movement of the mouse-type input device in a first direction and a first distance results in the cursor moving the first direction and a corresponding second distance.

  • Publication number: 20040153987
    Abstract: An embodiment of the invention provides an improved method and system for joining computer-generated rectangles by a mask designer. The improved method first selects the first rectangle to be connected and connects a second rectangle to the first. Next, an orthogonal route is traced to the third rectangle to be connected by identifying specific points between the first and the third rectangles. After identifying the orthogonal route, the area around the last specified point is zoomed in on. Next, the third rectangle is identified. Finally, after identifying the third rectangle, the second is connected to the first and third rectangles with the same width as the width of the first or third triangle and the length defined by the orthogonal route.

  • Patent number: 6433576
    Abstract: A circuit for altering a chip pad signal incorporates a primary driver that is configured to deliver a chip pad signal to an IC package. The circuit also is configured to cooperate with a second signal and a third signal, with the second signal having a voltage higher than the voltage of the first logic high, and the third signal having a voltage lower than the voltage of the first logic low. So configured, the primary driver may selectively deliver a second logic high, which has a voltage higher than the voltage of the first logic high, to the IC package, and may selectively deliver a second logic low, which has a voltage lower than the voltage of the first logic low, to the IC package. Electronic devices, systems and methods also are provided.
