Abstract
An improved current detection start-up circuit for a reference voltage circuit which restarts a reference voltage circuit when a reference voltage drops by a predetermined level, i.e., turns off, due to noise or a variation of a system voltage. The circuit includes: a current detection circuit for detecting the current being applied to a reference voltage circuit; and a start-up circuit for starting the reference voltage circuit when the current detected by the current detection circuit is below a predetermined level.
