Abstract:
Systems, methods and apparatus for efficient power control and/or compensation with respect to a varying supply voltage of an RF amplifier for amplification of a constant envelope RF signal are described. A reduction in a size of a pass device of an LDO regulator is obtained by removing the pass device of the LDO regulator from a main current conduction path of the RF amplifier. Power control and/or compensation is provided by varying one or more gate voltages to cascoded transistors of a transistor stack of the RF amplifier according to a power control voltage. Various configurations for controlling the gate voltages are presented by way of a smaller size LDO regulator or by completely removing the LDO regulator. In a case where a supply voltage to the transistor stack varies, such as in a case of a battery, a compensation circuit is used to adjust the power control voltage in view of a variation of the supply voltage, and therefore null a corresponding drift/variation in output power of the RF amplifier.

Claim (Index 16):
The circuital arrangement according to  claim 2 , further comprising:\n a gate voltage control module coupled to gates of the one or more transistors of the stack, wherein: the gate voltage control module is configured to provide, based on a control voltage, the nominal gate voltage of the at least one gate voltage independently from remaining gate voltages of the one or more transistors of the cascoded transistors of the stack.
