Abstract
Apparatus and methods for power control in mobile communication devices are provided. In one aspect, a wireless communication device includes a transmit chain that receives a digital in-phase (I) signal and a digital quadrature-phase (Q) signal and that generates a transmit signal. The wireless communication device further includes a power amplifier that amplifies the transmit signal, and a transmit chain controller including a reference generator that combines the digital I signal and the digital Q signal and generates a reference signal corresponding to an instantaneous value of an envelope of the combined signal. The transmit chain controller further includes an error extractor that generates an error signal based on the reference signal and an output power of the power amplifier, and a control signal generator that uses the error signal to generate one or more power control signals for controlling an adjustable power level of the transmit chain.
