Abstract:
An integrated circuit device, comprising:a first bipolar transistor; a second bipolar transistor that is positioned to be adjacent to the first bipolar transistor; a first wiring that is electrically connected to an emitter of the first bipolar transistor and extends therefrom into a direction opposite to the second bipolar transistor with respect to the first bipolar transistor; and a second wiring that is electrically connected to an emitter of the second bipolar transistor and extends therefrom into a direction opposite to the first bipolar transistor with respect to the second bipolar transistor, wherein the first bipolar transistor and the second bipolar transistor form a differential amplification circuit, the first bipolar transistor and the second bipolar transistor are positioned to be substantially axially symmetrical to each other, and the integrated circuit device further includes a third wiring that is electrically connected to a base of the first bipolar transistor and is substantially parallel to the axis of symmetry, and a fourth wiring that is electrically connected to a base of the second bipolar transistor and is substantially parallel to the axis of symmetry.
