ABSTRACT:
A two-stage differential amplifier connected in cascade according to the present invention is suitable for fabrication within an integrated circuit, in which a constant current source circuit is connected with the common emitters of the transistors in the preceding stage differential amplifier, and the emitters of the transistors in the succeeding stage differential amplifier are connected with the collectors of these transistors through impedance elements. Current consumption in the overall amplifier is reduced and heat production therein is suppressed. Furthermore, since a capacitor is connected between the collector of each of the transistors in the preceding stage differential amplifier and the base of each of the transistors in the succeeding stage differential amplifier, it is possible to match easily the input and the output impedances in the succeeding and preceding amplifier by means of this capacitor and the impedance elements described above.
