    摘要: Offset voltages developed on floating nodes on inputs to high-performance amplifiers that are DC isolated from the data signals input to amplifiers are cancelled by connecting a highly resistive element between the input node and a predetermined potential, particularly useful in proximity communication systems in which two chips are connected through capacitive or inductive coupling circuits formed jointly in the two chips. The resistive element may be an off MOS transistor connected between the node and a desired bias voltage or a MOS transistor with its gate and drain connected to the potential. Multiple bias voltages may be distributed to all receivers and locally selected by a multiplexer for application to one or two input nodes of the receiver. The receiver output can also serve as a predetermined potential when the resistive element has a long time constant compared to the data rate or the resistive element is non-linear.

    摘要: One embodiment of the present invention provides a method that reduces power consumption by using capacitive coupling to perform a majority detection operation. The method involves 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. In addition, method involves feeding a 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 method further involves using 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 a computer system.

    摘要: In a proximity communication system, transmit elements on one chip are aligned with receive elements on a second chip juxtaposed with the first chip. However, if the elements are misaligned, either statically or dynamically, the coupling between chips is degraded. The misalignment may be compensated by controllably degrading performance of the system. For example, the transmit signal strength may be increased. The bit period or the time period for biasing each bit may be increased, thereby decreasing the bandwidth. Multiple coupling elements, such as capacitors, may be ganged together, thereby decreasing the number of channels. The granularity of symbols, such as images, may be increased by decreasing the number of bits per symbol. Multiple coupling elements, such as capacitors, may be ganged together, thereby decreasing the number of channels.

    摘要: A phase-interpolator circuit is described. In the phase-interpolator circuit, an output signal, having a fundamental frequency and a phase, is generated based on a weighted summation of a first reference signal and a second reference signal, where the first reference signal has the fundamental frequency and a first phase, and the second reference signal has the same fundamental frequency and a second phase. Note that contributions of the first reference signal and the second reference signal, respectively, to the output signal are determined based on associated first and second impedance values in a weighting circuit in the phase-interpolator circuit. For example, a programmable capacitance ratio of two capacitors may be used to interpolate between the first reference signal and the second reference signal. Additionally, the phase-interpolator circuit may include a biasing circuit that provides a DC bias to the weighting circuit, and which amplifies the output of the weighting circuit to provide the output signal.

    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 memory module is formed of multiple memory chips and an optical interface chip fixed on a substrate. The chips are interconnected by proximity communication (PxC) in which each chip includes transmitting and receiving elements, such as electrical pads which form capacitively coupled links when the chips are placed together with their pads facing each other. The PxC links may be directly between the chips or through an intermediate passive bridge chip. The interface chip is coupled to an external optical channel and includes converters between optical and electrical signals, control circuitry, buffers, and PxC elements for communicating with the memory chips. The array of memories may be a linear or two-dimensional array around the interface chip forming a redundant PxC network, optionally with redundant PxC connections. Multiple rectangular memory chips may present their narrow sides to the interface chip to maximize bandwidth.

    摘要: One embodiment of the present invention provides a system that facilitates biasing receiver circuits within an integrated circuit. During operation, the system provides n receiver circuits within the integrated circuit to be biased. Next, the system provides n+m communication channels between n drivers and n receivers, wherein m is a number of additional communication channels, and wherein m>0. Then, the system couples the n+m communication channels to the n drivers, wherein each driver is selectively coupled to m+1 communication channels. The system also couples the n+m communication channels to the n receivers, wherein each receiver is selectively coupled to m+1 communication channels. In this way, at any given time n of the communication channels are active and m of the communication channels are inactive. Finally, the system refreshes inactive m communication channels' biases while the m inactive communication channels are not communicating signals.
