Abstract
A voltage multiplier circuit for raising an input voltage to a predetermined voltage is characterized in that a plurality of multiplier cells for raising an input voltage to be outputted, and a connection switching circuit for switching a connection state of these multiplier cells are provided, and the connection switching circuit connects multiplier cell groups formed by connecting one or a plurality of the multiplier cells, in parallel to an output, and varies the number of the multiplier cells of the multiplier cell groups and that of the multiplier cell groups.
