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 3):
The power amplifier system of  claim 1 , wherein the valley detector circuit comprises:\n a supply input corresponding to a supply level of the supply voltage; and a peak detection circuit to detect a peak level of the signal output and a high frequency AC amplitude level of the power amplifier circuit, wherein the valley detector circuit generates the detection output according to a difference between the peak level and the high frequency AC amplitude level.
