摘要： Die-to-die interconnect structures are leveraged to form the inductive component of an LC oscillator, thus yielding an LC tank distributed across multiple IC dies rather than lumped in a single die. By this arrangement, reliance on area/power-consuming on-chip inductors may be reduced or eliminated, and phase-aligned clocks may be extracted from the LC tank within each of the spanned IC dies, obviating multiple oscillator instances or complex phase alignment circuitry.

摘要： A phase detector circuit compares the phases of first and second periodic input signals to generate an output signal. The phase detector includes a circuit that makes two different combinations of the first and the second periodic input signals to generate third and fourth periodic signals. This circuit causes the third periodic signal to be based on a first combination of the first periodic signal and the second periodic signal that imparts a first relative phase shift. The circuit causes the fourth periodic signal to be based on a second combination of the first periodic signal and the second periodic signal to provide a different relative phase shift. The phase detector also includes a comparison circuit that compares a measure of the power of the third periodic signal to a measure of the power of the fourth periodic signal to generate the phase comparison output signal.

摘要： A method of tracking a second electronic device with respect to a first electronic device is disclosed. The method includes transmitting a first waveform of a first frequency along a first fixed path associated with the first device. A second waveform having a frequency based on the first frequency is wirelessly transmitted from the first device to the second device along a first wireless path. The second waveform is wirelessly transmitted from the second device to the first device along a second wireless path. The first and second waveforms are received at the phase comparator circuit. A first phase relationship of the received first waveform is then compared to a second phase relationship of the received re-transmitted waveform. A coordinate of the second device is determined with respect to a reference coordinate based on the comparing.

摘要： A near-field communication (NFC) system supports increased data rates using a multiple-input-multiple-output (MIMO) interface. Multiple receive antennas are positioned within the near field of multiple transmit antennas. The NFC system uses a combination of antenna spacing and polarizations to reduce correlation between channels, and thus improves performance by creating closer to ideal MIMO operation. Such system can also be operated as parallel SISO links with reduced cross-channel interference resulting in low power consumption.

摘要： In a system that employs multiple air movers (e.g., fans) within an enclosure, the air movers are controlled in an attempt to optimize cooling efficiency of the system. In some aspects, current cooling efficiency is indicated based on one or more characteristics of an acoustic signature in the enclosure. In particular, a reduction in cooling efficiency may be indicated by spreading of an acoustic peak of the acoustic signature. Accordingly, improved cooling efficiency may be achieved by controlling the air movers in a manner that reduces spreading of such an acoustic peak.

摘要： Passive signal combiners are employed to transform at least one signal from one domain to another. In some aspects the transformation comprises an NFL an IFFT, a DFT, or an IDFT. In some implementations the passive signal combiners comprise a set of planar waveguides (e.g., which may be referred to as beamformers or Rotman lenses) that have multiple inputs and outputs and are configured to provide orthogonal output signals. In some implementations an electrical signal (e.g., received via an antenna element) is coupled to passive beamformers that transform the electrical signal from one domain to another domain. Here, a transformation of the electrical signal by a given passive beamformer may have a first resolution, and outputs from the passive beamformers may correspond to orthogonal groups. A combiner circuit may be used to combine the outputs from the passive beamformers and produce a combined output having a second resolution and an associated error. In some aspects, this error may be less than a cumulative error associated with the passive beamformers if a single passive beamformer was instead employed to transform the electrical signal at the second resolution. Also, by using at least partially different bandwidths for components in the circuits, a higher effective bandwidth for the transformation may be achieved.
摘要翻译：被动信号组合器用于将至少一个信号从一个域转换到另一个域。在某些方面，转换包括NFL，IFFT，DFT或IDFT。在一些实施方式中，无源信号组合器包括具有多个输入和输出并且被配置为提供正交输出信号的一组平面波导（例如，其可以被称为波束形成器或Rotman透镜）。在一些实现中，电信号（例如，经由天线元件接收）耦合到无源波束形成器，其将电信号从一个域转换到另一个域。这里，给定无源波束形成器的电信号的变换可以具有第一分辨率，并且被动波束形成器的输出可以对应于正交组。可以使用组合器电路来组合来自无源波束形成器的输出，并产生具有第二分辨率和相关误差的组合输出。在某些方面，如果采用单个无源波束形成器来以第二分辨率转换电信号，该误差可能小于与被动波束形成器相关联的累积误差。此外，通过对电路中的组件使用至少部分不同的带宽，可以实现用于转换的较高有效带宽。
