摘要： A method for calibrating an offset voltage of an amplifier used to amplify capacitively coupled communication signals is described. During this process, a common voltage is applied to one or more inputs to the amplifier. Next, an output of the amplifier is iteratively, measured, and charge is applied to the one or more inputs until the offset voltage is less than a pre-determined value. Note that applying the charge may involve applying a sequence of one or more charge pulses.

摘要： One embodiment of the present invention provides a system that reduces power consumption by using capacitive coupling to perform a majority detection operation. The system starts by driving a plurality of signals onto a plurality of driven wires. The signals are then fed from each driven wire through a corresponding coupling capacitor to a single majority detection wire. Next, the system feeds signal on the majority detection wire and a bias voltage to a differential receiver. The output of the differential receiver switches if the signal on the majority-detection wire switches relative to the bias voltage. The system then uses the output of the differential receiver to optimize the signals from the plurality of driven wires for transmission across a long signal route. Optimizing the transmission of signals reduces the power consumed by the computer system.

摘要： One embodiment of the present invention provides a system that facilitates reducing the power needed for proximity communication. This system includes an integrated circuit with an array of transmission pads that transmit a signal using proximity communication. A layer of fill metal is located in proximity to this array of transmission pads, wherein the layer of fill metal is “floating” (e.g., not connected to any signal). Leaving this layer of fill metal floating reduces the parasitic capacitance for the array of transmission pads, which can reduce the amount of power needed to transmit the signal.

摘要： One embodiment of the present invention provides a system that facilitates high-bandwidth communication using a flexible bridge. This system includes a chip with an active face upon which active circuitry and signal pads reside, and a second component with a surface upon which active circuitry and/or signal pads reside. A flexible bridge provides high-bandwidth communication between the active face of the chip and the surface of the second component. This flexible bridge provides a flexible connection that allows the chip to be moved with six degrees of freedom relative to the second component without affecting communication between the chip and the second component. Hence, the flexible bridge allows the chip and the second component to communicate without requiring precise alignment between the chip and the second component.

摘要： A system that fabricates a semiconductor chip. The system places patterns for components which require fine line-widths within a high resolution region of a reticle, wherein the high resolution region provides sharp focus for a given wavelength of light used by the lithography system. At the same time, the system places patterns for components which do not require fine line-widths outside of the high-resolution region of the reticle, thereby utilizing the region outside of the high-resolution region of the reticle instead of avoiding the region. Note that the coarseness for components placed outside of the high resolution region of the reticle is increased to compensate for the loss of optical focus outside of the high resolution region.

摘要： A system that dynamically refreshes the inputs of a differential receiver. During operation, while a differential transmitter is not transmitting data, the system applies substantially equal voltages to the outputs of the differential transmitter so that the differential voltage on the outputs of the differential transmitter is substantially zero. The system then refreshes the inputs of an associated differential receiver by applying substantially equal voltages to the inputs of the differential receiver so that the differential voltage on the inputs of the differential receiver is substantially zero. The differential transmitter is coupled to the differential receiver through a DC blocking mechanism, which prevents a DC voltage on the differential transmitter from reaching the differential receiver.
