Abstract:
Adaptive rail power amplifier technology processes an audio signal by feeding the audio signal to the power amplifier to produce an output signal, applying positive and negative power supply voltages centered with respect to the audio signal to the positive and negative power supply rails of the power amplifier, comparing the output signal with the positive and negative power supply rail voltages to produce dynamically varying positive and negative control signals, feeding the positive and negative control signals to positive and negative high current charge pumps and adding supplemental positive and negative voltages from the positive and negative charge pumps to the positive and negative power supply rails to produce a linear adaptive rail voltage which tracks the output signal.
