Abstract:
Techniques are described for using valley detection for supply voltage modulation in power amplifier circuits. Embodiments operate in context of a power amplifier circuit configured to be driven by a supply voltage generated by a supply modulator and to receive an amplitude-modulated (AM) signal at its input. The output of the power amplifier circuit can be fed to a valley detector that can detect a valley level corresponding to the bottom of the envelope of the AM signal. The detected valley level can be fed back to the supply modulator and compared to a constant reference. In response to the comparison, the supply modulator can vary the supply voltage to the power amplifier circuit in a manner that effectively tracking the envelope of the power amplifier circuit's output signal, thereby effectively seeking a flat valley for the output signal's envelope.

Claim (Index 11):
A power amplifier system comprising:\n means for amplifying an output signal by applying gain to an input signal and applying a common mode DC level to the output signal according to a supply voltage; and means for regulating the supply voltage to dynamically track an amplitude envelope of the output signal as a function of dynamically detecting a valley level of the output signal, the means for regulating comprising means for gating the means for regulating, such that the supply voltage dynamically tracks the amplitude envelope of the output signal only when the supply voltage is above a predetermined minimum supply voltage level.
