This reactance circuit comprises a differential amplification circuit formed by differentially connecting the first (1) and second (2) transistors to each other, a load (4) connected to a collector of the first transistor, a reactance element (5) interposed between a base of the first transistor and a reference potential point (A), and a capacitor (8) and a resistor (9). connected in series between the collector and the base of the first transistor. A negative feedback loop to the first transistor is formed by the capacitor and the resistor. Accordingly, when the collector of the first transistor is used as an output terminal, a negative equivalent reactance is produced in the output terminal. |
