摘要： Systems and methods of low power clocking of sleep mode radios are disclosed herein. In an example embodiment, a crystal oscillator is purposefully mistuned to achieve lower power consumption, and then synchronized using a high frequency crystal oscillator. In an alternative embodiment, the input offset voltages of the comparator in an RC oscillator are cancelled, which allows low power operation and high accuracy performance when tuned to the high frequency crystal. A lower power comparator may be used with higher input offset voltages but still achieve higher accuracy. The RC circuit is switched back and forth on opposite phases of the output, cancelling the offset voltage on the inputs of the comparator.
摘要翻译： 本文公开了睡眠模式无线电的低功率时钟的系统和方法。 在一个示例性实施例中，晶体振荡器有目的地失灵以实现较低的功耗，然后使用高频晶体振荡器进行同步。 在替代实施例中，RC振荡器中的比较器的输入偏移电压被消除，当调谐到高频晶体时，这允许低功率操作和高精度性能。 可以使用较低功率的比较器，具有更高的输入失调电压，但是仍然可以获得更高的精度。 RC电路在输出的相反相位来回切换，消除比较器输入端的失调电压。

摘要： A system and method integrates signal filters in a multiband transceiver. A preferred embodiment comprises an amplifier with a first tunable capacitor coupled to a signal input and a tunable filter. The tunable filter comprises an input stage with a first pair of inductors arranged in a dipole configuration and a second tunable capacitor coupled in parallel to the first pair of inductors and an output stage inductively coupled to the input stage, the output stage includes a second pair of inductors also arranged in a dipole configuration and a third tunable capacitor coupled in parallel to the second pair of inductors. The inductors are realized using bond wire or any other high Q material. The first tunable capacitor, the second tunable capacitor, and the third tunable capacitor can be tuned using a master-slave tuning configuration to adjust the operating frequency of the amplifier and the tunable filter to enable frequency band compatibility with multiple communications protocols.

摘要： A system and method for channelization and data multiplexing in ultra-wideband (UWB) wireless communication system is described. The spectrum allocated for UWB in a multi-band OFDM (orthogonal frequency division multiplex) system is subdivided into various bands. A set of time frequency codes (TFC's) is defined, wherein each code specifies one of a plurality of unique band versus time sequences for a particular band group, for sequential data symbols of a given piconet. The separation of data words from multiple devices or multiple simultaneously operating piconets (SOP's) is provided by a combination of FDMA and TFC's. The combination of FDMA and TFC's provides a simplified interface between the MAC and PHY.
