摘要 介绍了一种应用在音频系统的ΣΔpower DAC。对整个ΣΔpower DAC的设计进行了详细的介绍,实际的硬件用Synopsys工具进行了完整的电路设计、仿真和版图设计。在MP3中得到实际应用,音质效果良好。 A high precision sigma-delta power digital-to-analog converter has been designed for audio application. Some keys of the design, circuit details and simulation results are presented in this paper. Circuit of the sigmadelta power DAC has been designed, simulated and implemented by Synopsys tools. The design has been adopted in MP3 products. The performance is perfect.
