Switched capacitor regulators with flying-inverter-controlled power switches

摘要

A switching capacitor regulator, comprising: a switching capacitor configured to switch between a first state and a second state, wherein, in the first state, a first node of the switching capacitor is coupled to a second terminal, and a second node of the switching capacitor is coupled to a fixed voltage level, and wherein, in the second state, the first node is coupled to a first terminal, and the second node is coupled to the second terminal; a power switch configured to couple the second node to the second terminal when the switching capacitor is in the second state; and a flying inverter configured to control the power switch, wherein the flying inverter has a positive power terminal and a negative power terminal, wherein the positive power terminal is coupled to the first node, and wherein the negative power terminal is coupled to the second node.
