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： An optical connector is described. This optical connector spatially segregates optical coupling between an optical fiber and an optical component, which relaxes the associated mechanical-alignment requirements. In particular, the optical connector includes an optical spreader component disposed on a substrate. This optical spreader component is optically coupled to the optical fiber at a first coupling region, and is configured to optically couple to the optical component at a second coupling region that is at a different location on the substrate than the first coupling region. Moreover, the first coupling region and the second coupling region are optically coupled by an optical waveguide.

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 of protecting a proximity communication system against electrostatic discharge (ESD). The proximity communication system includes two chips, each having an array of electrical pads at its surface and covered by a thin dielectric layer such that capacitive coupling circuits are formed between the chips when they are joined together. In at least one of the chips, an additional protection pad is formed away from the array, and heavy protection circuitry is connected to it. Its surface is exposed through the dielectric surface over it such that, when an ESD aggressor approaches, the discharge occurs to the protection pad.

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.

摘要： A diversity proximity communication system formed on two juxtaposed chips, one having a two-dimensional array of transmit elements, the other having a two-dimensional array of receive elements. The receive and transmit elements need not be aligned and may have nominal alignment of one transmit element overlapping the corners of four receive elements. The elements may be electrical pads capacitively coupled across the interface. Signals of four different multiplexing groups, e.g., time-multiplexed, are supplied to transmitting elements in a 2×2 array. Signals from four receive elements in a 2×2 array are amplified, combined, and demultiplexed for the selected multiplexing group. The gains for the four signals to be combined are differentially controlled to increase the signal-to-noise ratio. The amplification may be determined by the overlap between each of the receive elements and the transmit element of the selected multiplexing group.

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 signals using proximity communication. This array is comprised of a set of macropads, where each given macropad is comprised of a set of micropads that can be configured to transmit a signal. A steering fabric routes signals to and within macropads, such that a subset of the micropads in the array can be configured to transmit the signal to a receiving component. Each macropad receives a limited number of input signals, with the steering fabric routing input signals to the micropads of the macropads. By limiting the number of input signals that are routed to the micropads of the macropads, the steering fabric eliminates redundant steering configurations for the array and reduces the power needed to transmit the signal.

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.
