Abstract: Examples provide a method for clock calibration. A wireless communication device includes a first clock and a second clock. The first clock is turned off but the second clock runs during the inactive state of the wireless communication device. A frequency offset of the first clock is measured with respect to a reference frequency based on a signal received from a network. A virtual timer, which is a software-based timer is updated based on the frequency offset. A drift of the second clock is measured over a predetermined time interval based on the virtual timer. The virtual timer is restored based on the drift after wake-up from the inactive state. Alternatively, a clock frequency relation between the first clock and the second clock may be measured and a phase locked loop (PLL) may be controlled based on the measured clock frequency relation.

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.
