ABSTRACT:
In a reference voltage generating circuit having an improved temperature compensation function, a PMOS transistor forming a constant voltage circuit has the same characteristics as a PMOS transistor forming a negative feedback circuit. As an ambient temperature changes, gate-source voltage and drain current characteristics of each transistor are shifted, but temperature compensation is achieved by appropriately setting a drain current of each transistor. Transistors for the temperature compensation can be formed in the same manufacturing steps, so that temperature compensating effect can be obtained without an additional manufacturing step.
