Low-power digital audio (Class-D) amplifiers are widely used in portable digital devices, such as MP3 players and smart phones. ΔΣ modulators are suitable for Class-D amplifiers, because high-order modulators provide better performance and low cost. However, for higher-order ΔΣ modulator design, it is imperative to determine the optimal design parameters… CONTINUE READING
