  • Patent number: 7536107
    Abstract: A laser driver for high speed interconnections may convert a digital signal to a current train of a bias mode to represent logical zero and of a modulation mode to represent logical one. An optical signal thus produced may include an optical offset. An optical receiver may include a photo-detector to receive the optical signal and generate a current signal, which includes a corresponding current offset. A first amplifier stage converts the current signal to a voltage signal and a second amplifier stage generates a digital output from the voltage signal. One or more low-pass filters may be used to filter the digital output and generate a filtered offset signal for a differential amplifier to generate an offset cancellation signal. The offset cancellation signal may be provided to offset cancellation circuitry to remove the current offset from the current signal generated by the photo-detector.

  • Patent number: 7528619
    Abstract: A voltage droop detector captures the very high-frequency noise on the power grid of a load, such as a microprocessor. The droop detector includes twin circuits, one of which receives the voltage from the power grid of the load, the other of which receives a filtered voltage. A 0th droop, as well as 1st droops, 2nd droops, and so on, are captured and stored for subsequent analysis. The circuits sample the voltages frequently enough to ensure that all droop events are captured. Other embodiments are described and claimed.

  • Patent number: 7505497
    Abstract: One embodiment of a laser driver for high speed interconnections includes a buffered level shifter to shift the input voltage level to an appropriate level. In some embodiments the buffered level shifter may be tuned to provide a desired level shift with impedance matched to the driving load. Another embodiment converts a digital signal to a current train of a bias mode to represent logical zero and of a modulation mode to represent logical one, wherein one or both of the bias mode and modulation mode may be adjusted, for example by a programmable control circuit or by an adaptive control circuit. Some embodiments also provide circuitry for reducing overshoot of the output signal.

  • Patent number: 7501316
    Abstract: Some embodiments provide a memory cell that includes a body region, a source region and a drain region. The body region is doped with charge carriers of a first type, the source region is disposed in the body region and doped with charge carriers of a second type, and the drain region is disposed in the body region and doped with charge carriers of the second type. The body region and the source region form a first junction, the body region and the drain region form a second junction, and a conductivity of the first junction from the body region to the source region in a case that the first junction is unbiased is substantially less than a conductivity of the second junction from the body region to the drain region in a case that the second junction is unbiased.

  • Patent number: 7391640
    Abstract: A dynamic random access memory includes a cell having a circuit between a floating-body transistor and a bit line. Activation of the circuit is controlled to provide isolation between the floating body and bit-line voltage both during write operations and during times when the cell is unselected. The added isolation improves performance, for example, by reducing the need for gate-to-body coupling and the magnitude of voltage swings between the bit lines.
