<p>To realize a low-distortion amplifier suitable for a wideband amplifier in which the level of a generated jamming signal can be controlled so that it is low even if multiple signals different in a frequency are amplified, an amplifier according to the present invention is provided with an amplifying element (1) provided with an input terminal(S) and the output terminal D wherein relationship between input voltage supplied to the input terminal S and output current flowing to the output terminal D is provided with a nonlinear characteristic in which as the input voltage is increased, the differential coefficient of the output current increases and a two-terminal element (5) provided with two terminals d and s wherein relationship between voltage applied between the two terminals d and s and current flowing between the two terminals d and s is relationship in which as the applied voltage is increased, the differential coefficient of the current decreases, and characterized in that one end d of the two-terminal element (5) is connected to the input terminal S of the amplifying element (1), an input signal is supplied to the other end s of the two-terminal element (5) and output current flowing to the output terminal D of the amplifying element (1) flows to the two-terminal element (5) via the input terminal S. <IMAGE></p> |
