The proposed SCVR achieves 190 ps transient FoM with peak conversion efficiency of 83.7%@114.2 mA/mm2 and 110× supported loading range of 80 μA-8.8 mA. ? 2021 JSAP.Approximation algorithmsApproximation theoryConversion efficiencyEfficiencySwitching frequencyVLSI circuitsVoltage regulatorsEfficiency enhancement techniqueFully integratedMulti rateRegulation algorithmsSuccessive approximationsSwitched capacitorSwitched capacitor DC-DCDC-DC converters[SDGs]SDG3[SDGs]SDG7conference paper10.23919/VLSICircuits52068.2021.94923332-s2.0-85111882012
