摘要:
A reversible, switched capacitor voltage conversion apparatus includes a plurality of individual unit cells coupled to one another in stages, with each unit cell comprising multiple sets of inverter devices arranged in a stacked configuration, such that each set of inverter devices operates in separate voltage domains wherein outputs of inverter devices in adjacent voltage domains are capacitively coupled to one another such that a first terminal of a capacitor is coupled to an output of a first inverter device in a first voltage domain, and a second terminal of the capacitor is coupled to an output of a second inverter in a second voltage domain; and wherein, for both the first and second voltage domains, outputs of at least one of the plurality of individual unit cells serve as corresponding inputs for at least another one of the plurality of individual unit cells.
