摘要

本文设计了一种50mhz 5v输入3w输出的3电平降压变换器。提出了一种实时飞行电容(CF)校准方法，以确保CF上的Vg/2电压恒定，这是确保可靠性和保持3电平变换器优势的必要条件。在65nm制程的测量中，观察到0.6-4.2V的宽输出范围，90%的峰值效率和23-29ns/V的参考跟踪响应。在启用所提出的校准后，实现了显着降低的VO纹波。

A 50MHz 5V 3W 90% efficiency 3-level buck converter with real-time calibration and wide output range for fast-DVS in 65nm CMOS

In this paper, a 50-MHz 5-V input 3-W output 3-level buck converter is presented. A real-time flying capacitor (CF) calibration is proposed to ensure a constant Vg/2 voltage across the CF, which is essential to ensure the reliability and maintain the advantages of 3-level converters. A 0.6-4.2V wide output range, a 90% peak efficiency and a 23-29ns/V reference tracking response are observed in measurements with 65nm process. A significantly reduced VO ripple is achieved after enabling the proposed calibration.
