摘要:
A wireless network device having active and inactive modes comprises a clock generating module that generates a first clock signal having a first clock rate. A voltage supply module generates a first voltage level and a second voltage level that is less than the first voltage level. A first digital module receives the first clock rate and the first voltage level during the active mode, receives the second voltage level during the inactive mode and does not receive the first clock signal during the inactive mode. A first analog module communicates with the voltage supply module and has reduced current consumption during the inactive mode.

A voltage regulator comprises a master regulator circuit that receives a reference signal and that generates a feedback signal and a master bias signal. The master bias signal is based on the reference signal and the feedback signal. N slave regulator circuits receive the master bias signal from the master regulator circuit and output N regulated output signals to N circuits, respectively, where N is an integer greater than one.

The present disclosure describes techniques for identity-based RF circuitry compensation. In some aspects data from a wireless device is received via radio frequency circuitry, the data including an identifier that uniquely identifies the wireless device. Impairments of the radio frequency circuitry are estimated based on the received data and then the estimated impairments are associated with the identifier of the wireless device. In response to subsequently receiving data that includes the identifier, the radio frequency circuitry is compensated using the estimated impairments.

Circuits and methods are provided for adjusting a frequency of a local clock signal in approximating a frequency of a host clock signal. A phase locked loop generates a local clock signal having a first phase and a first frequency. An offset adjustment circuit receives timing information relating the local clock signal to an incoming data signal and calculates a phase offset and a frequency offset indicative of adjustments to be made to the local clock signal. A first phase interpolator generates a receive clock signal from the local clock signal, the receive clock signal having a second phase and a second frequency responsive to the phase and frequency offsets. A second phase interpolator generates a transmit clock signal from the local clock signal having a third frequency responsive to the frequency offset.
