摘要： An integrated circuit has a plurality of sections, each having a phase detector and a control delay circuit. The phase detector, in response to a phase difference between a reference clock signal and a feedback signal from a portion of a clock grid, controls the delay of its associated clock delay circuit, which, in turn, outputs to the portion of the clock grid. The feedback signal to the phase detector may be connected to an output of a DLL or another portion of the clock grid controlled by a clock delay circuit not associated with the phase detector. Such an arrangement on the integrated circuit leads to clock grid skew reduction.

摘要： A method and apparatus for post-fabrication adjustment of a delay locked loop leakage current is provided. The adjustment system includes an adjustment circuit that adjusts a leakage current offset circuit to compensate for the leakage current of a capacitor in the delay locked loop. The capacitor connects to a control voltage of the delay locked loop. Such control of the leakage current in the delay locked loop allows a designer to achieve a desired delay locked loop operating characteristic after the delay locked loop has been fabricated.

摘要： A Mobile Subscriber Directory Assistance (MSDA) system including originating carrier center initiating a directory assistance call, a directory assistance center providing a directory assistance service, and a search environment. The search environment includes an aggregated pointer database and at least one directory number resolution database. A caller requesting a telephone number is connected to a directory assistance service center where search criteria for the requested number are taken. The requested number is identified by searching the aggregated pointer database and the directory number resolution database. The caller is connected to the identified telephone number without releasing this identified telephone number.

摘要： A method and apparatus to determine skew of an on-chip signal without physical probing of the on-chip signal on the chip is provided. The method and apparatus use an externally generated reference signal that is distributed to one or more on-chip samplers that input the on-chip signal. Then, by modulating the externally generated reference signal, transitions of the on-chip signal can be detected at the one or more on-chip samplers so that the skew of the on-chip signal can be determined.
