Abstract: Methods, systems, and circuitries are provided to generate clock signals of different qualities in a device. A method includes determining whether the device is operating in a mid power mode or a high power mode. In response to determining that the device is operating in the mid power mode, oscillator circuitry is controlled to cause the oscillator circuitry to consume a lower amount of power, such that the oscillator circuitry generates a lower quality clock signal. In response to determining that the device is operating in the high power mode, the oscillator circuitry is controlled to cause the oscillator circuitry to consume a higher amount of power, such that the oscillator circuitry generates a higher quality clock signal. The lower amount of power and the higher amount of power are different from one another.

Abstract: Methods and devices for allocating power among a plurality of circuits in a communication device, including determining a power budget for allocating to the plurality of circuits from a power supply information; receiving an activity status from a first circuit of the plurality of circuits; determining a first power value based on the activity status; deriving a second power value based on the first power value and the power budget; and allocating power to one or more remaining circuits of the plurality of circuits based on the second power value.
