Title:
SIGNAL SYNTHESIS CIRCUIT, DIGITAL AUDIO AMPLIFIER, AND POWER SUPPLY CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2013/047550
Kind Code:
A1
Abstract:
The present invention has a slope generation circuit and a one-bit determination circuit. A first one-bit digital signal is inputted to the slope generation circuit, which generates a slope for the first one-bit digital signal while the first one-bit digital signal is transitioning from high to low and/or while the first one-bit digital signal is transitioning from low to high. An analog signal and the output signal from the slope generation circuit are inputted to the one-bit determination circuit, a high-low determination performed on the output signal from the slope generation circuit varies depending on the analog signal, and the one-bit determination circuit outputs a second one-bit digital signal generated on the basis of said high-low determination.
