초록
This paper presents the design of a single chip digital audio amplifier based on delta-sigma modulation and a power-efficient swithing output stage. The amplifier uses a fouth-order switched-capacitor high performance delta-sigma modulator with a 1bit quantizer and designed in standard 0.18um CMOS process.
