    摘要： An energy efficient radio having a clocking system utilizing two clocks with very different precision and power characteristics. In another aspect, the time that a radio spends on listening/receiving is optimized so that energy is not wasted when there is no need to keep receiving. In another aspect, to further improve the energy efficiency, two receive portions with drastic difference in power consumption, instead of a single receive portion as is used in a typical wireless receiver, and are used to process different parts of a received packet.

    摘要： Local clock modeling for a discrete event simulator is described. A local clock generator provides realistic clock characteristics in terms of clock precision and clock drift and clock mapping utilities provide API for other modules and/or protocols in the discrete event simulator to schedule events on local clocks instead of global clock of the simulator.

    摘要： In high current integrated circuit wafer test applications, a high capacitance density capacitor may be formed in association with a probe card at a position closer to a wafer under test. This reduces the power path impedance, improving transient power delivery of a probe card. That is because now the capacitance is positioned more closely to the wafer under test, reducing path impedance. The capacitance density may be at higher, improving transient power delivery.
