Abstract
A reference voltage generator generates a reference voltage having a stable voltage level insensitive to a temperature variation. A reference voltage generator includes a current generating unit configured to generate a reference current proportional to temperature increase, a voltage adjusting unit configured to adjust a reference voltage corresponding to a current level of the reference current, and a start-up driving unit configured to drive and amplify the reference voltage while the voltage adjusting unit operates.
