Abstract

PURPOSE: To remove failure due to unbalance of ground potential at each grounding point, by taking the symmetrical neutral point at PP reception end of common base type and a complementary type PP current source as an output terminal, and adjusting the gain with a load resistor.
CONSTITUTION: A voltage signal inputted to a terminal 33 of a voltage-current conversion section 1 is inputted to a noninverting input terminal 7 of a preamplifier 3, the phase is inverted and the output of the same phase and amplitude is obtained from terminals 9 and 10. Alternate amplification is made with transistors (TR)12, 17 and TRs 13, 18, the output is grounded 24 with a resistor 21 from a neutral point 37 and is given to an inverting input terminal 8 of the amplifier 3 via a feedback circuit 4. The output of the terminals 9, 10 is amplified at the TRs 13, 18 and applied to complementary type elements 29, 30 of a current-voltage conversion 2 via terminals 25, 26. With this constitution, a voltage proportional to an input signal between an input terminal 33 and a grounding point 22 of the section 1 is obtained between an output terminal 34 of the convesion section 2 and the grounding point 23, and the relation of proportion is not effected entirely even if a potential fluctuation between the grounding points 22 and 32 is in existence for transmission with fidelity.
