REFERENCE VOLTAGE GENERATOR AND INTEGRATED CIRCUIT INCLUDING A REFERENCE VOLTAGE GENERATOR

摘要

A reference voltage generator and an integrated circuit including the reference voltage generator. The reference voltage generator includes a band gap reference circuit and a start-up circuit. The band gap reference circuit provides a reference voltage to a load. The start-up circuit increases the provided reference voltage by providing a boosting current to the load based on a difference between the provided reference voltage and a target reference voltage responsive to a start-up signal, thereby reducing a time in which the provided reference voltage reaches the target reference voltage. Therefore, the reference voltage generator is configured to provide a target reference voltage within a predetermined time.
