  • SYSTEM, METHOD AND APPARATUS FOR SUPPORTING MULTI-MODE AMPLIFIER FOR MULTIPLE WIRELESS COMMUNICATION PROTOCOLS
    Publication number: 20260171981
    Abstract: In one aspect, an apparatus includes a power amplifier comprising a plurality of slices configurable to: amplify a first radio frequency (RF) signal of a first wireless protocol according to a linear mode of operation; and amplify a second RF signal of a second wireless protocol according to a non-linear mode of operation. The apparatus further includes a programmable impedance circuit coupled to an output of the power amplifier, where the programmable impedance circuit is to be controlled based on a power level of the power amplifier.

  • SYSTEM, METHOD AND APPARATUS FOR SUPPORTING MULTI-MODE AMPLIFIER FOR MULTIPLE WIRELESS COMMUNICATION PROTOCOLS
    Publication number: 20260171979
    Abstract: In one aspect, an apparatus includes: a dual-mode power amplifier to amplify a first radio frequency (RF) signal of a first wireless protocol according to a linear mode of operation, and to amplify a second RF signal of a second wireless protocol according to a non-linear mode of operation; at least one digital feedback circuit coupled to the power amplifier, the at least one digital feedback circuit to provide feedback information; and a controller to control a power level of the dual-mode power amplifier based at least in part on the feedback information.

  • User interface enabling approval/disappoval of revised contract performance indicators
    Patent number: 8533027
    Abstract: A user interface and processes are provided to monitor contracts for the delivery of products and/or services to different customers. The user interface provides a comprehensive visual display such that a user can view multiple contracts and a variety of performance information for each contract. The user interface also enables a user to update performance indicators for a contract and to identify contracts that require heightened scrutiny or action to mitigate current problems or potential issues.

  • Sigma-delta modulator including truncation and applications thereof
    Patent number: 7969341
    Abstract: A multi-stage sigma-delta modulator including bit truncation between stages. The bit truncation reduces the number of bits that must be processed in subsequent stages and thus allows for faster response times. In some embodiments, the gain of a feedback loop is selected to compensate for the bit truncation such that the sigma-delta modulator operates in a stable state.
