    摘要： A method of routing a metal layer trace in an integrated circuit die includes steps of: (a) receiving as input a netlist of an integrated circuit die; (b) selecting a redistribution layer trace from the netlist for routing the redistribution layer trace between an I/O pad of the integrated circuit die and a termination point; (c) comparing a trace width of the redistribution layer trace with a maximum trace width limit; and (d) if the trace width of the redistribution layer trace exceeds the maximum trace width limit, then routing the redistribution layer trace as a plurality of separate parallel traces each having a trace width that is less than the selected maximum trace width limit.

    摘要： An optical receiver, for use for instance in an analog optical communications system such as a return path in cable television, operates over a wide range of input power to its photodetector. This is accomplished by providing in the optical receiver a series of RF amplifier stages where at least one of the stages includes a fixed attenuator and a parallel amplifier with switches suitably connected so that, at any one time, only one of the fixed attenuator or the amplifier is in the signal path. The switches are controlled so that the dynamic range of the optical receiver is improved in order to make gain reduction more accurate. Hence by redirecting the RF signal path to either the attenuator or amplifier of the amplifier stage, excessive noise and distortion by the amplifier stage are eliminated or reduced.

    摘要： One of a plurality of base stations is selected by a network entity, such as a mobile control point, for communicating with a respective remote station. Transmission channel quality information associated with at least two of the base stations is received at predefined intervals. Loading information associated with the base stations is received at further predefined intervals. A respective one of the base stations is selected as a function of the quality information and the loading information. An indication that the respective remote station is to commence communication with the selected one of the at least two base stations is sent to the respective remote station.
