摘要

采用psrr增强的ab类耳机放大器的低功耗地参考音频解码器在整个音频频带中对负电荷泵的电源纹波的THD < 0.0016%。在40nm CMOS中实现的全集成立体声解码器在驱动16Ω耳机负载的同时实现了91dB SNDR和100dB动态范围，并从1.8V电源消耗5.2mW。核心区域仅为0.093mm2/通道。

A 5.2mW, 0.0016% THD up to 20kHz, ground-referenced audio decoder with PSRR-enhanced class-AB 16Ω headphone amplifiers

A low-power ground-referenced audio decoder with PSRR-enhanced class-AB headphone amplifiers presents <;0.0016% THD in the whole audio band against the supply ripple by a negative charge-pump. Realized in the 40nm CMOS, the fully-integrated stereo decoder achieves 91dB SNDR and 100dB dynamic range while driving a 16Ω headphone load and consumes 5.2mW from a 1.8V power supply. The core area is 0.093mm2/channel only.
