Abstract
An embodiment of the present invention comprises a voltage regulator including a droop compensation circuit and a voltage regulator circuit. The droop compensation circuit compensates for an output that changes over a period of time. This variable output may be the result of voltage regulator droop and/or a load transistor droop. For instance, the voltage regulator droop may be associated with the decrease in regulator output voltage that occurs during the course of applying a load. The load transistor droop may correspond to the decrease in RF transistor gain that occurs over the course of a transmit pulse. The variable output could be attributable to other phenomena. Moreover, the variable output that is compensated for is not necessarily decreasing over time, but, in fact, could be increasing over time, or could exhibit increases and decreases over time.
