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 5):
The power amplifier system of  claim 1 , further comprising:\n a pushdown detector circuit to detect whether the valley level is pushed below a predetermined minimum valley level; and a limiter circuit coupled with the pushdown detector circuit and the power amplifier circuit to limit the gain applied to the signal input in response to the pushdown detector circuit detecting that the valley level is pushed below the predetermined minimum valley level.
