Abstract
In a wide-band amplifier circuit, a third and a fourth transistors are cascaded externally with a first and a second transistors within an integrated circuit which are connected each to output terminals by collectors through the output terminals, and a collector current flowing in the third transistor is transformed into an output voltage by an external resistance. A load capacity parasitic on the output terminal of the integrated circuit is driven by the collector current, thus a possibility of a frequency characteristic deteriorating due to an influence of the load capacity is avoided, and an operating zone can further be expanded to a high frequency band as compared with a prior art one.
