该论文提出了一种基于片上铁电电容的可重构开关电容DC-DC转换器，通过利用铁电电容的高介电常数和低寄生效应，实现了93%的高效率。解决了传统开关电容转换器中因寄生电容和导通损耗导致的效率受限问题。
Dynamic Voltage Scaling (DVS) has become one of the standard techniques for energy efficient operation of systems by powering circuit blocks at the minimum voltage that meets the desired performance [1]. Switched Capacitor (SC) DC-DC converters have gained significant interest as a promising candidate for an integrated energy conversion solution that eliminates the need for inductors [2,3]. However, SC converters efficiency is limited by the conduction loss, bottom plate parasitic capacitance, gate drive loss in addition to the overhead of the control circuit. Reconfigurable SC converters supporting multi-gain settings have been proposed to allow efficient operation across wide output range [2,4]. Also, High density deep trench capacitors with low bottom plate parasitic capacitance have been utilized in [5] achieving a peak efficiency of 90%. In this work, we exploit on-chip ferroelectric capacitors (Fe-Caps) for charge transfer owing to
