摘要:
Embodiments of the invention may provide for enhancement systems and methods for a power amplifier output control system. In an example embodiment, driver amplifier control may be provided in conjunction with power amplifier control to improve the power efficiency and/or dynamic range of the transmitter system. Furthermore, control over the driver amplifier may allow for relaxed power control slope, which may lessens the burden of digital to analog converters (DACs) in transmitter systems such as cellular transmitter systems. Also, systems and methods in accordance with example embodiments of the invention may provide a less sensitive solution to operational environment variations such as temperature, battery power voltage and implementation IC process.
