    • Methods and systems are provided for frequency generation suitable for use in wireless devices capable of operating at multiple frequencies. Such systems may change the loop gain of an automatic frequency control loop based on the operating frequency of the wireless device. Furthermore, such a frequency dependent loop gain may be carried out by the selection of subroutines with differing loop gains associated with the subroutines. Furthermore, the loop gain may also be temperature compensated based on the temperature of the wireless device and/or the operating frequency of the device.
    • 用于频率生成的方法和系统可以在能够在多个频率上操作的无线设备中实现。 本发明的系统尤其可以根据无线设备的工作频率来修改自动频率控制环路的增益。 频率相关回路增益的这种修改可以通过选择子程序来完成,与这些子程序相关的回路的不同增益。 取决于无线设备的温度和/或该设备的操作频率,环路的增益可以进一步被温度稳定。
