ABSTRACT:
When an input terminal, which is connected to an input transistor, is opened, a transistor having an emitter connected to the input transistor conducts to supply constant current to a constant current source which is connected to the emitter of the input transistor. Therefore, load current of a reference circuit connected to the constant current source is not changed even if the input terminal is opened. As the result, current valves of all constant current sources receiving voltage from the reference circuit are not changed so that the internal circuit of a semiconductor integrated circuit device can be stably operated.
