    Abstract: A tracker circuit configured to provide a variable supply voltage to a power amplifier (PA) circuit is disclosed. The tracker circuit includes a state machine circuit comprising a plurality of states mapped in accordance with transitions associated with a mapping scheme. In some embodiments, the plurality of states of the state machine circuit identify one or more operational modes associated with the tracker circuit, wherein at least one operational mode comprises one or more voltage levels respectively associated therewith. In some embodiments, the one or more operational modes includes at least two active operational modes. In some embodiments, a transition between the one or more operational modes of the tracker circuit is controlled by a digital selection signal received from a digital communication interface associated therewith.

    Abstract: Currently, transmission power of a STA in multi-user uplink environment is determined by the AP without addressing STA considerations that relate to voltage, power use, power saving, overhead, etc., and in general relate to the STA's power consumption (All of which can have secondary effects such as interference, etc.). By adopting the protocol and/or the restriction on assigned transmission power per STA, better power consumption can be achieved for the STA. In accordance with an exemplary embodiment, techniques are disclosed that employ the concept of such a restriction and a protocol, as well as a technique and device to implement the concept.
