ABSTRACT:
Embodiments relate to a start-up circuit for a reference voltage generation circuit. According to embodiments, a start-up circuit may include a start-up start unit allowing current to flow in the reference voltage generation circuit to initiate a start-up process in response to a start-up start signal, a reference current generation unit decreasing a variable voltage depending on whether the reference voltage generation circuit is started up and generating start-up reference current corresponding to the variable voltage, and a start-up controller detecting current flowing in the reference voltage generation circuit, comparing the detected result with the start-up reference current, and outputting the compared result as a start-up start signal. Current consumption may be decreased after start-up. A BRG circuit may be stably started up. If a high supply voltage is used, current consumption may decrease, and if a low supply voltage is used, a BGR circuit may be stably started up.
