Abstract

PURPOSE: To transmit signals with fidelity, by taking the symmetrical neutral point of a complementary PP circuit as an output terminal, connecting it to a load to form a voltage-current convesion section, and transmitting a signal to a current- voltage conversion section.
CONSTITUTION: When a signal is inputted to a noninverting input terminal 7 of a preamplifier 3 via a terminal 33 of a voltage-current conversion section 1, the phase is inverted and the same phase and amplitude outputs are obtained from terminals 9, 10. The outputs are alternately amplified at transistors(TR)12, 17 and TRs 13, 18, this output is grounded 24 with a resistor 21 from a neutral point 37 and applied to an inverting input terminal of the amplifier 3 via a feedback circuit 4. The output of terminals 9, 10 is amplified at the TRs 13, 18 and grounded 32 via a load 31 of a current-voltage conversion section via terminals 25, 26. With this constitution, even with unbalanced ground potential, a input signal between an input terminal 33 of the voltage-current conversion section and a ground 22 can be transmitted between the output terminal 34 and the groud 32 of the current-voltage conversion section with fidelty.
