    摘要： In a system 10 for designing an integrated circuit, a preliminary design of the integrated circuit is defined and critical interconnect lines in the preliminary design are identified. Further, any critical interconnect lines which are affected by crossing lines in the preliminary design are identified, and a transmission line model 35 is defined to represent each critical interconnect line. A layout design of the integrated circuit, comprising circuit components and parameters thereof, is then defined using the preliminary design and the transmission line model 35 for each critical interconnect line. Component parameters are then extracted from the layout design for simulation of the design using the extracted component parameters. During this design process, for each transmission line model 35 representing a critical interconnect line affected by a crossing line, an environment terminal 36 is provided. The environment terminal 36 comprises a connection to the model 35 via at least one circuit component representing the effect of the crossing line on the model. The environment terminal 36 is connected to the appropriate crossing line in the integrated circuit design, whereby crossing line effects are accommodated in the design process.

    摘要： A radio signal based object location system is provided wherein location devices are provided on articles for use in locating the articles, and wherein a database is maintained relating characteristics of radio signal transmissions between the location devices and fixed devices to locations within an area. A method is provided for maintaining the database to reflect propagation conditions. Location devices are provided at fixed positions within the area. Data representing radio signal transmission characteristics between the fixed position location devices and fixed devices is recorded. Transmissions between the fixed position location devices and the fixed devices is monitored to determine changes in the characteristics of radio signal transmissions from the recorded data.

    摘要： A switched capacitor circuit, including a load-capacitor, and a charging switch which is coupled to apply a potential to the load-capacitor. The circuit further includes a compensating-capacitor and switching circuitry which is coupled to the charging switch and the compensating-capacitor and which is switchable. The switching is arranged to transfer to the compensating-capacitor an injection error charge produced by the charging switch, and then to isolate the injection error charge on the compensating-capacitor from the load-capacitor.

    摘要： Instrumentation driver apparatus, including a main driver, coupled to receive an alternating input signal and having a main circuit structure, which is adapted to generate, in response to the alternating input signal, a main output signal with alternating voltage. The apparatus includes a mirror driver, coupled to receive a direct voltage input and having a mirror circuit structure located in proximity to the main circuit structure, which is adapted to generate a mirror output signal in response to the direct voltage input, such that a variation in an operating condition of the main driver causes a corresponding variation in the mirror output signal. The apparatus further includes a feedback circuit, coupled to receive the mirror output signal, which provides in response to the mirror output signal a feedback stabilization input to the main driver so as to stabilize the main output signal.
