摘要： Embodiments described herein provide circuitry employing one or more inductors having an unconventional turn-ratio. The circuitry includes a primary inductor having a first length located on a first layer of an integrated circuit (IC). The circuitry further includes a secondary inductor having a second length located on a second layer of the IC different from the first layer, whereby the second length is greater than the first length, with a ratio between the first and the second lengths corresponding to a non-integer turn-ratio.

摘要： A directional coupler for a wireless communication device includes a first input port, a first output port, a second input port, a second output port, and a coupled port. The first input port and the first output port are respectively configured to receive and provide a first signal to be transmitted from the wireless communication device. The second input port and the second output port are respectively configured to receive and provide a second signal to be transmitted from the wireless communication device. A coupled port is configured to selectively provide a coupled signal corresponding to each of, in respective modes, the first signal and the second signal.

摘要： In some implementations, a system includes a voltage regulating circuit and a compensation circuit. The voltage regulating circuit includes a pass element configured to provide a regulated voltage to a load. The compensation circuit is configured to adjust a variable resistance based on a current of the load, the variable resistance being coupled to a gate terminal of the pass element through a capacitor.

摘要： Different scan modes are provided for Bluetooth devices. In at least some embodiments, a narrowband scanning mode looks for signal energy on individual transmission frequencies at a time. By looking for signal energy rather than decoding transmitted packets, at least some of the components in a Bluetooth device can remain in an idle or rest state. A midband scanning mode looks for signal energy across multiple different frequencies at a time. Again, by looking for signal energy across multiple different frequencies rather than decoding transmitted packets, at least some of the components in a Bluetooth device can remain in an idle or rest state. A wideband scanning mode looks for signal energies across all relevant frequencies at a time. At least some embodiments enable a Bluetooth device to switch between scanning modes.
摘要翻译：为蓝牙设备提供了不同的扫描模式。在至少一些实施例中，窄带扫描模式一次在单个传输频率上寻找信号能量。通过寻找信号能量而不是解码发送的分组，蓝牙设备中的至少一些组件可以保持在空闲或休眠状态。中频扫描模式一次查找多个不同频率的信号能量。再次，通过在多个不同的频率上寻找信号能量而不是解码传输的分组，蓝牙设备中的至少一些组件可以保持在空闲或静止状态。宽带扫描模式一次查找所有相关频率的信号能量。至少一些实施例使得蓝牙设备能够在扫描模式之间切换。
