Abstract
A reference voltage generator includes an output terminal, a current source, a reference circuit, a protection circuit, and a control circuit. The output terminal outputs a reference voltage. The current source is coupled to the output terminal, and generates a reference current. The reference circuit is coupled to the output terminal, and generates a reference voltage according to the reference current. The protection circuit is coupled to the output terminal, and adjusts a voltage of the output terminal to an operating voltage. The control circuit is coupled to the reference circuit and the protection circuit. The control circuit controls the reference circuit and the protection circuit according to a start signal.
