Abstract: An initial voltage generation circuit includes a reference voltage generator, a reference voltage selector, at least one initial voltage level regulator, and a plurality of stabilization capacitors. The reference voltage generator generates a plurality of reference voltage candidate groups. The reference voltage selector includes a plurality of selection switch groups and a plurality of switch control circuits. Each selection switch group includes a plurality of parallel switches.
