ABSTRACT:
A reference voltage generator, and a method thereof, supplies a reference voltage to a device that decides between first and second output levels based on the reference voltage. The reference voltage generator includes a reference current unit through which a reference current flows and a replica unit. An input terminal of the replica unit is connected to the reference current unit. An output terminal of the replica unit is connected to the device. The replica unit includes a replica circuit replicating a circuit in the device that decides the first output level. The replica unit multiplies the first output level from the replicated circuit in response to the reference current by a predetermined ratio and outputs the result as the reference voltage to the device.
