摘要： Coupled multi-inductors and their applications. An apparatus includes several circuit stages. Each circuit stage includes an inductive element that overlaps with the inductive elements of its adjacent circuit stages, forming a loop of coupled circuit stages. The apparatus may be, for example, a multi-phase oscillator with multiple oscillators that are magnetically coupled to each other for generating oscillation signals at different phases. The apparatus may also be, for example, a phase interpolator for combining input signals.

摘要： Described are integrated signal interfaces that include receive amplifiers and termination elements. Termination control circuitry calibrates the impedances through the termination elements to take into account the transconductance of the receive amplifiers. Transconductance bias circuitry can be used to bias the receive amplifiers, and the bias can be derived from a reference voltage. The interfaces can derive the common-mode voltage from received signals as the reference voltage, rather than from a dedicated voltage reference.

摘要： A decision feedback equalizer is calibrated to compensate for estimated inter- symbol interference in a received signal and offsets of sampling devices. The decision feedback equalizer is configured so that an output signal of a sampling circuit represents a comparison between an input signal and a reference of the sampling circuit under calibration. An input signal is received over a communication channel that includes a predetermined pattern. The predetermined pattern is compared to the output signal to determine an adjusted reference for configuring the sampling circuit that accounts for both offset and inter-symbol interference effects.

摘要： A transceiver includes a transmitter and receiver that form a series current path between two power- supply nodes. Powering both the transmitter and receiver with the same supply current saves power. The transmitter functions as a resistive load for the receiver, and thus performs useful work with power that would otherwise be dissipated as waste heat.

摘要： High resolution output drivers having a relatively small number of sub-driver branches or slices each having nominal impedances substantially larger than a quantization step and that incrementally differ from one another by an impedance step substantially smaller than a quantization step. In one implementation, such "differential" or "non¬ uniform" sub-driver slices implement respective elements of an n choose k equalizer, with each such differential sub-driver slice being implemented by a uniform-element impedance calibration DAC. In another implementation, each component of a uniform-slice equalizer is implemented by a differential-slice impedance calibration DAC, and in yet another implementation, each component of a differential-slice equalizer is implemented by a differential-slice impedance calibration DAC. In an additional set of implementations, equalization and impedance calibration functions are implemented bilaterally in respective parallel sets of driver branches, rather than in the nested "DAC within a DAC" arrangement of the hierarchical implementations. Through such bilateral arrangement, multiplication of the equalizer and calibrator quantizations is avoided, thereby lowering the total number of sub-driver slices required to meet the specified ranges and resolutions.
摘要翻译：高分辨率输出驱动器具有相对较少数量的子驱动器分支或切片，每个分切器或切片具有基本上大于量化步长的标称阻抗，并且通过基本上小于量化步长的阻抗步长递增地彼此不同。在一个实现中，这种“差分”或“非均匀”子驱动器片实现n选择k均衡器的相应元件，每个这种差分子驱动器片由均匀元件阻抗校准DAC实现。在另一个实现中，均匀片均衡器的每个组件由差分片阻抗校准DAC实现，并且在又一个实现中，差分片均衡器的每个组件由差分片阻抗校准DAC实现。在另外一组实施方式中，均衡和阻抗校准功能是在各自并行的驱动器分支组中双侧实现的，而不是在分层实现中嵌套的“DAC内的DAC”布置中。通过这种双边配置，避免了均衡器和校准器量化的乘法，从而降低了满足指定范围和分辨率所需的子驱动器片的总数。

摘要： An electronic device for wirelessly tracking the position of a second electronic device is disclosed. The electronic device includes transceiver circuitry having a beacon generator to generate a beacon at a particular frequency and direction. An antenna array transmits the beacon, and receives at least one reflected beacon from the second electronic device. The reflected beacon is received if a position of the second electronic device lies within a range of directions of the beacon. The transceiver circuitry further includes an injection-locked oscillator having an input coupled to the antenna array to receive reflected beacons, and to lock to the reflected beacon when the reflected beacon has a frequency value within locking range of the oscillator. Processing circuitry coupled to the transceiver circuitry tracks the position of the second device based on the lock condition of the oscillator.
