摘要
This invenu00c7u00c3o is fully digital audio power amplifiers, converters switched multinu00cdvel (1,2) in the waterfall fed by log (3,4) in radiographic geometric of reason fraccionu00c1ria (3 / 2, for example), capable of providing nine levels of voltage of SA u00cdda (muitinu00cdvel) with a cascade of two converters.And including reduction of distortion of the stages do not realimentadas power by extending narrow pulses (5,6). The invenu00c7u00c3o is aimed to obtaining of amplifiers with fully digital processing multibit with attributes of high income, low distortion and reduction of energy in the band of frequencies above the band audu00cdvel.This invenu00c7u00c3o materializes digital amplifiers for audio power amplifiers with the best performance comparu00c1vel power for audio analu00d3gicos known, keeping the high performance amplifiers inherent to class D.
