摘要

将音频和电源管理集成到片上系统(SoC)中，可以减少电路板面积和成本。集成的d类音频驱动器需要驱动高电压，以便在小负载下提供高功率;525mW (5.8Vpp差)，通过8Ω负载工作在电池上。缺乏高压晶体管以及高器件噪声(闪烁)，器件失配和泄漏给45nm CMOS的设计带来了挑战。

45nm CMOS 8Ω Class-D audio driver with 79% efficiency and 100dB SNR

Integrating audio and power management into a system-on-chip (SoC) is of interest due to reduced board area and cost. Integrated Class-D audio drivers need to drive high voltages to deliver high power across small loads; 525mW (5.8Vpp differential) across an 8Ω load working off the battery. Absence of high-voltage transistors along with high device noise (flicker), device mismatch and leakage pose design challenges in 45nm CMOS.
