Abstract

PURPOSE: To almost zero a grounding current and to increase the distortion factor and to reduce crosstalk, by detecting the grounding current given to a load with a resistor through the amplification of an input signal, and absorbing the grounding current through the amplification of it.
CONSTITUTION: An input signal is amplified at an amplifier 4, and a current flows to a grounding terminal 9 via load 3 and a current detecting resistor 11. An output terminal of an amplifier 20 is negative through a voltage drop by the current detecting resistor 11, and the current flowing via the load 3 is absorbed via a resistor 30. Thus, the grounding current of a grounding line 10 can almost be zeroed.
