Abstract
To down size a distortion-correcting circuit. In the case of a distortion-correcting circuit, a basic-wave-amplifying sectionand a distortion-extracting sectionhave the same circuit configuration. Therefore, the basic-wave-amplifying sectionand the distortion-extracting sectionhave almost equal input impedance and output impedance and make it possible to distribute and synthesize signal powers without using any power distributor or any power synthesizer. Moreover, because the distortion-correcting circuitis constituted by only a transistor, a resistance, a capacitor, or an inductor, it is easy to downsize the circuitand constitute the circuitinto an integrated circuit. Therefore, a characteristic of the basic-wave-amplifying sectionand that of the distortion-extracting sectionare further similar to each other and it is possible to more properly distribute or synthesize signal powers without using any power distributor or any power synthesizer.
