本文提出了一种具有细粒度电压转换比（VCR）的全集成开关电容（SC）DC-DC转换器，采用算法电压馈送技术，实现了0.22V至2.4V的宽输入电压范围。该转换器通过系统化的VCR生成，解决了传统SC转换器因VCR有限导致效率波动大的问题。
Instituto Superior Tecnico/University of Lisboa, Lisbon, Portugal 1 2 Most existing switched-capacitor (SC) DC-DC converters only offer a few voltage conversion ratios (VCRs), leading to significant efficiency fluctuations under wide input/output dynamics (e.g. up to 30% in [1]). Consequently, systematic SC DCDC converters with fine-grained VCRs (FVCRs) become attractive to achieve high efficiency over a wide operating range. Both the Recursive SC (RSC) [2,3] and Negator-based SC (NSC) [4] topologies offer systematic FVCR generations with high conductance, but their binary-switching nature fundamentally results in considerable parasitic loss. In bulk CMOS, the restriction of using low-parasitic MIM capacitors for high efficiency ultimately limits their achievable power density to <1mW/mm2. This work reports a fully integrated fine-grained buck-boost SC DC-DC converter with 24 VCRs. It features an algorithmic voltage-feed-in (AVFI)
