An open-loop class-D audio amplifier with the proposed adaptive-coefficient delta-sigma modulator (ACDSM) and low-EMI control method is implemented in a 0.18μm BCD process. Compared with conventional DSMs, the ACDSM simultaneously achieves a wide stable input range and high in-band noise suppression, resulting in a 20% increase of low-distortion(More)
