Abstract

PURPOSE:To prevent an influence of nonlinear distortion, by providing the first impedance and the second impedance, between an inverted input terminal and an output terminal of an amplifier, and between a noninverted input terminal and an output terminal, respectively. CONSTITUTION:Inverted input terminal voltage of an amplifier 22 whose amplification degree is A, output voltage, impedance of circuits 23, 24, and voltage across a load 5 are made V', V'', Z1 and Z2, and V0, respectively. In this case, there is relation of V'=(AV0+Z1i1)/(1+A), Z2i2=(A-1)V0AV', from which Z2i2=-V0/ (1+A)-AZ1Z2/(1+A) is obtained. At this time, when A is made infinity , Z2i2=-Z1i1 is derived, and a current transfer function is i2/i1=-Z1/Z2. In this case, V0 becomes i2ZL, and even if a nonlinear element is used for the circuits 23, 24, it exerts no influence on the amplifier.
