摘要： A communications apparatus and method use tapped delay lines as multiplexers and demultiplexers. In one embodiment, a receiver (100) uses a tapped delay line (110) as a demultiplexer to acquire a burst communication at very high data rates in the range of 2.5 to 80 Gbps with low preamble overhead. A sliding window correlator (114) continually samples the delay line (110) to determine when a PN encoded word is contained therein. The transmission frequency is pre-acquired before any data is present through the use of a ring oscillator frequency calibration loop (130) that is imbedded within the tapped delay line (110).

摘要： A semiconductor device, a microelectromechanical system package and a method of making the same utilize high performance vias for vertical IC packaging. A semiconductor die of the device/package has a substrate with integrated circuitry formed on a front side of the substrate. A metal bonding pad overlies the substrate on the front side of the substrate and is electrically connected to the integrated circuitry. A solder bump is located on the metal bonding pad. An electrically conductive via extends through the substrate from the metal bonding pad to a back side of the substrate where the via forms a side wall of a via hole. A plurality of the substrates are stacked on one another with the outer end of the solder bump of one substrate fitting within the via hole of an adjacent substrate. During reflow soldering, surface tension forces of the molten solder bump self-align the substrates.

摘要： A signal equalizer that employs micro-electromechanical machine devices for the tap weight controllers. The equalizer includes a substrate on which is formed a forward transmission line rail and a return transmission line rail. A cantilever stanchion is also formed on the substrate that runs parallel with the transmission line rails. A series of spaced apart cantilevers are pivotally mounted to the cantilever stanchion, and extend over the transmission line rails to define a gap therebetween. A weight tap line is coupled to each cantilever, and is responsive to a DC weight signal that controls the position of the cantilever to set the gap between the cantilever and the transmission line rails. A distorted signal is coupled from the forward transmission line rail to the return transmission line rail through the cantilevers.

摘要： A configurable circuit array that includes a matrix of cells, where each cell includes interconnected analog and/or digital circuit elements. The cells are fabricated on a common semiconductor substrate, and are electrically isolated from each other. The circuit elements in the cells are electrically coupled to circuit elements in other cells, and are electrically coupled to bonding pads by coaxial transmission lines capable of transmitting extremely high frequency signals. The transmission lines include a center conductor and first and second shield conductors, where the shield conductors prevent cross-talk interference. The transmission lines extend vertically from the substrate until they are a suitable distances above the circuit elements in the cell. From there, the transmission lines extend horizontally relative to the substrate to the opposite end connection point, where they again extend vertically down to the substrate.

摘要： In an analog-to-digital converter (100), a method and apparatus compare (302) an analog input signal (102) with a reference signal (108) to generate a decision signal (110), and sum (304) the analog input signal with a control value (130) whose magnitude is determined by an accumulated value (126), and whose sign is determined by the decision signal, thereby generating an error signal (114). The method and apparatus further calculate (306) a correlation value (118) between the error signal and the decision signal, and accumulate (308) the correlation value to produce the accumulated value, thereby adaptively compensating for an inaccuracy in the A/D converter.

摘要： An optical device for use with an optical input beam comprising an optical thresholding device positioned along an optical path defined by the propagation direction of the optical input beam. If the combined intensity of the optical input beam and a control beam exceeds a threshold level, the optical beam passes through the thresholding device. Preferably, the optical thresholding device is a saturable absorber. When the device is configured as an optical comparator, the intensity of the optical input beam exceeds the threshold level and the thresholding device saturates and turns transparent so that the control beam passes through the thresholding device as an optical indicator beam. When the device is configured as an optical signal attenuator and the intensity of the optical input signal is negligible compared to that of the control beam, the combined intensity of the beams does not saturate the thresholding device.

摘要： An optical device for use with an optical input beam comprises and optical thresholding device having a predetermined threshold level, and is positioned along an optical path defined by the propagation direction of the optical input beam. A source generates a control beam through the optical thresholding device, wherein if the combined intensity of the optical input beam and the control beam is large enough to exceed the threshold level of the thresholding device, the optical beam passes through he thresholding device. The thresholding device attenuates the optical beam as it passes therethrough. In a preferred embodiment, the optical thresholding device is a saturable absorber. When the device is configured as an optical comparator, the intensity of the optical input beam is large enough to exceed the threshold level of the thresholding device, the thresholding device saturates and turns transparent so that the control beam passes through the thresholding device as an optical indicator beam and the optical input beam passes through the thresholding device. When configured as an optical signal attenuator and the intensity of the optical input signal is negligible compared to that of the control beam the combined intensity of the optical input signal and the control beam do not saturate the thresholding device.

摘要： An orthogonal pilot tone servo controller provides a servo control loop for each tap in a delay line processor where each servo acquires its independence from the other tap's servos utilizing an orthogonal code set modulated on top of the existing tap values. The orthogonal codes are attenuated in amplitude such that the code sets are transparent to the processed signals of interest, but the code's length enables each tap's servo controller to independently recover the tap's state from the aggregate of signals and codes through processing gain realized in each loop's recovery circuit. A plurality of taps can be thus be servo controlled simultaneously, providing for extremely wide bandwidth processes which can be performed accurately with digital controls.

摘要： An optical quantizer (10) that employs a chain of optical thresholding devices (16) positioned in the propagation path of an optical input beam (12) to be quantized. Each optical thresholding device (16) saturates and turns transparent if the intensity of the optical beam (12) that impinges it is above a predetermined threshold level designed into the device (16). If the input beam (12) saturates the optical thresholding device (16), the device (16) outputs an indicator signal (22) identifying the saturation. The input beam (12) propagates through the optical thresholding device (16) with some attenuation caused by the saturation, and impinges subsequent optical thresholding devices (16) in the chain. Eventually, the attenuation of the input beam (12) caused by the multiple saturations will decrease the beam intensity below the threshold level of the next optical thresholding device (16). The number of indicator signals (22) gives an indication of the intensity of the input beam (12). The optical thresholding devices (16) can provide optical or electrical indicator signals (22) depending on the type of thresholding device (16) used.

摘要： A transmitter-receiver includes a transmitting circuit for providing an output by converting the frequency of a transmission signal input thereto, a receiving circuit for providing an output by converting the frequency of a received signal input thereto, and a local oscillator which generates an oscillation signal having a local oscillating frequency based on a reference signal. A local oscillator signal splitter is connected to the local oscillator and splits the oscillation signal into substantially similar transmit and receive oscillation signals each at the local oscillating frequency. The local oscillator signal splitter supplies the transmit oscillation signal to the transmitting circuit and supplies the receive oscillation signal to the receiving circuit. The transmitting circuit converts the frequency of the transmission signal in accordance with said transmit oscillation signal, and the receiving circuit converts the frequency of the received signal in accordance with the receive oscillation signal.
