ABSTRACT:
The signal output circuit1includes a first and a second emitter follower circuit, and a comparator20. The comparator20receives output signals from the first and the second emitter follower circuit, and outputs a result of comparison in magnitude between those signals. The comparator20includes a transistor T5(fifth transistor), a transistor T6(sixth transistor), a resistance element R3, and a current mirror circuit30. The resistance element R3connects the emitters of the transistor T5and of the transistor T6. To the collectors of the transistor T5and the transistor T6, the current mirror circuit30is connected.
