ABSTRACT:
A reference voltage generator for generating a reference voltage having a constant voltage level. The reference voltage generator comprises a high voltage generating circuit for generating a boost voltage boosted over the power voltage level; a clamping circuit for clamping the boost voltage below a constant voltage; a ripple preventing circuit for preventing tipple of the boost voltage clamped through the clamping circuit; and a voltage dividing circuit for outputting a reference voltage which is below the power voltage by lowering the boost voltage outputted through the tipple preventing circuit.
