摘要

比较了电压型连续导模降压变换器中不同实现方式对线性斜坡信号的音频磁化率的影响。时域电荷分析证明了不同方法在不同占空比下的优势。使用标准的0.35 μ m CMOS工艺进行了晶体管级模拟以验证结果。

Audio susceptibility aware ramp signal design on feedforward voltage-mode CCM buck converter

This paper compares the effect on audio susceptibility with different implementations on the linear ramp signal in voltage-mode continuous-conduction-mode buck converter. Time domain charge-based analysis has been performed to justify the advantage of different approaches in different duty ratios. Transistor level simulations have been performed using a standard 0.35µm CMOS process to verify the results.
