	abstract = {This work presents a switched-capacitor (SC) DC-DC voltage regulator that converts a 3.7V battery voltage down to ~0.8V in order to power the {\textquoteleft}brain{\textquoteright} SoC of a flapping-wing microrobotic bee. A cascade of two 2:1 SC converters offers high efficiency for a 4:1 conversion ratio. A charge recycling technique reduces the flying capacitor{\textquoteright}s bottom-plate parasitic loss by 50\% and overall conversion efficiency reaches 70\%. The output droop is less than 10\% of the nominal output voltage for a worst-case 47mA load step.},
