ABSTRACT:
According to this invention, a reference voltage generating circuit includes a first series circuit, a second series circuit, and a control circuit. The first series circuit is constituted by a first resistor, a first transistor, a second transistor, and the second resistor connected in series between power source terminals. The second series connection circuit is constituted by third and fourth transistors which have control electrodes respectively connected to a connection point between the first resistor and the first transistor and a connection point between the second resistor and the second transistor, are connected in series between the power source terminals, and have a common connection point serving as a reference voltage output terminal. The control circuit sequentially ON/OFF-controls the first and second transistors by a control signal.
