摘要

PURPOSE:To obtain complementary characteristics easily by connecting a transfer characteristic determining circuit to the output terminal of an operational amplifier, by providing a switching method between the output terminal and inverted input terminal, and by leading complementary characteristics out from each terminal through the switching of the switching method. CONSTITUTION:With switch circuit 9 closed, 100% feedback is provided to operational amplifier 4 and from output terminal 2, an output signal with characteristics F is obtained. With circuit 9 opened, transfer characteristic determining circuit 5 is connected to the negative feedback path of amplifier 4 via resistance 10, and consequently characteristics of an output signal obtained from output terminal 3 are shown by the expression (A0 is the bare gain of amplifier 4.), providing complementary characteristics to an output signal when circuit 9 is closed.
