摘要

这封信介绍了并相涡轮（PMT）技术，这是一种显著提高连续可缩放转换比（CSCR）开关电容电压调节器（SCVR）输出电流能力的方法。该研究还提出了一种独特的方法来实现与这些转换器的无通信联动，增强了它们在各种功率域大小上的可扩展性。本研究采用4nm级CMOS技术制造，单片电容式稳压器的电流密度为26A/mm2，峰值效率为88.5%。

A Monolithic 26 A/mm2 Continuously Scalable Conversion Ratio Switched-Capacitor Converter With Phase-Merging Turbo and Communication-Less Ganging

This letter introduces the phase-merging turbo (PMT) technique, a method which significantly augments the output current capability of a continuous scalable conversion-ratio (CSCR) switched-capacitor voltage regulator (SCVR). The research also proposes a unique method for implementing communication-free ganging with these converters, enhancing their scalability across a wide range of power domain sizes. Fabricated using a 4-nm class CMOS technology, this study achieves a current density of 26 A/mm2 for monolithic capacitive voltage regulators, and a peak efficiency of 88.5%.
