Abstract: TECHNIQUES FOR FABRICATING ANALOG AND DIGITAL CIRCUITS ON SEPARATE DIES AND STACKING AND INTEGRATING THE DIES WITHIN A SINGLE PACKAGE TO FORM A MIXED-SIGNAL IC THAT PROVIDESMANY BENEFITS. IN ONE ASPECT, THE ANALOG AND DIGITAL CIRCUITS ARE IMPLEMENTED ON TWO SEPARATE DIES 120, 130) USING POSSIBLY DIFFERENT IC PROCESSES SUITABLE FOR THESE DIFFERENT TYPES OF CIRCUITS. THE ANALOG AND DIGITAL DIES (120, 130) ARE THEREAFTER INTEGRATED (STACKED) AND ENCAPSULATED WITHIN THE SINGLE PACKAGE. BONDING PADS (120, 130) ARE PROVIDED TO INTERCONNECT THE DIES AND ENCAPSULATED WITHIN THE SINGLE PACKAGE . BONDING PADS (122, 132) ARE PROVIDED TO INTERCONNECT THE DIES AND TO CONNECT THE DIES TO EXTERNAL PINS .THE BONDING PADS MAY BE LOCATED AND ARRANGED IN A MANNER TO PROVIDETHE REQUIRED CONNECTIVITY WHILE MINIMIZING THE AMOUNT OF DIE AREA REQUIRED TO IMPLEMENT THE PADS. IN ANOTHER ASPECT, THE DIE-TO-DIE CONNECTIVITY MAY BE TESTED IN CONJUNCTION WITH A SERIAL BUS INTERFACE . FIGURE 3B, 3C, 4B

Abstract: The present invention is a novel and improved method and apparatus for performing position location in wireless communications system. One embodiment comprises a method for performing position location using a set of signals transmitted from a set of satellites including the steps of storing coarse search data, performing a coarse search on said coarse search data for each satellite from said set of satellites, receiving fine search data, performing a set of fine searches on said fine search data, each fine search being performed on a different time segment of said fine search data, and reporting results.

Abstract: A data Interface for transferring digital data between a host and a client over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control and presentation data. The signal protocol is used by link controllers configured to generate, transmit, and receive packets forming the communications protocol, and to form digital data into one or more types of data packets, with at least one residing in the host device and being coupled to the client through the communications path. The interface provides a cost-effective, low power, bi-directional, high-speed data transfer mechanism over a short-range "serial" type data link, which lends itself to implementation with miniature connectors and thin flexible cables which are especially useful in connecting display elements such as wearable micro-displays to portable computers and wireless communication devices.

Abstract: Searcher hardware is multiplexed to perform simultaneous searches in either an IS-95 CDMA mode or a GPS mode. In the IS-95 mode, the search hardware is time-multiplexed into a number of searcher time slices, each of which can generate a PN sequence to despread a data sequence. In the GPS mode, the search hardware is configured as a number of distinct GPS channels, each of which can generate a Gold code sequence for tracking a GPS signal from a particular GPS satellite. This configuration allows the searcher to perform multiple GPS signal searches simultaneously. Signal searching in both IS-95 and GPS modes is performed at significantly higher speeds compared to conventional searcher hardware. Moreover, the search hardware can be dynamically configured to operate in either the IS-95 or the GPS mode, eliminating the need for dedicated circuitry for each mode of operation.

Abstract: The present invention is a novel and improved method and apparatus for performing position location in wireless communications system. In one embodiment the invention comprises a method in a subscriber unit (10) for performing position location in a CDMA wireless communications system having a base station (12), the method comprising: receiving a position location request containing aiding information from the base station (12) over a first receive frequency; in response to the position location request, tuning a receiver (52, 54, 102, 104) of the subscriber unit (10) away from the first receive frequency to a position location frequency in order to receive position location information; and receiving information over the position location frequency and using the received information to perform a position location procedure, the method being characterized by: including data transition boundary information in the aiding information.
