ABSTRACT:
A first reference signal whose components have the same amplitude and are symmetrical is supplied to the bases of a first and second transistors, the collectors of which are each connected to a power supply. A first resistor is connected between the emitters of the first and second transistors. A first constant current source is connected to the emitter of the first transistor. A second reference signal of a constant amplitude is supplied to the bases of a third and fourth transistors, the collectors of which are each connected to a power supply. A second resistor different in resistance from the first resistor is connected between the emitters of the third and fourth transistors. A second constant current source is connected to both the emitters of the second and third transistors, while a fourth constant current source is connected to the emitter of the fourth transistor. These first, seocnd, and third constant current sources produce the same current.
