Title: Reference voltage generator

Abstract: A reference voltage generating circuit of the present invention includes a start-up circuit connected between a power supply voltage and a ground voltage for generating a start-up voltage, a bias current generating circuit connected between the power supply voltage and the ground voltage for generating a bias current in response to the start-up voltage, the bias current increasing in response to an increase in temperature, a current generator connected between the power supply voltage and a reference voltage generating terminal for generating a mirrored current of the bias current, and a load connected between the reference voltage generating terminal and the ground voltage for generating a reference voltage that increases in response to any increase in temperature regardless of variations in the level of the power supply voltage. Accordingly, the level of reference voltage generated increases in response to increases in temperature regardless of variations in the level of the power supply voltage.
