Abstract
PURPOSE:To largely boost a voltage with less number of parts in a boosting circuit by sequentially controlling the charge of capacitors of an arbitrary block from the capacitor of the block connected to the input terminal side from the capacitor of the arbitrary block. CONSTITUTION:Blocks each having a diode D, a capacitor C and a switch SW are connected, and the switches SW are sequentially opened or closed in response to a control signal Q from a flip-flop FF. In case that, when the control signal is ''0'', the capacitor C is charged, and when it is ''1'', the capacitor C is discharged, a voltage being approximately 8 times the output voltage can be obtained at the output terminal of the output capacitor C4 under the sequential control listed in the table.
