Title: Low-frequency amplifier circuit
Inventor: TARUYA SUGIO
IPC: H03F1/34
Filed: 2002-09-18
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem in the amplifier circuit that electric current, whose input signal was modulated (referred to as modulated current, hereinafter), flows into a power source circuit or the amplifier circuit and voltage generated by the modulated current and impedance of the circuit (modulated volatage, hereinafter) causes adverse affect to another circuit or the self circuit.  <P>SOLUTION: By using a circuit 100, that consists of a voltage follower circuit 151 and circuits (152, 153), which control the sum of current at a constant level by negative feedback, a signal having a magnitude equal to electric current passing via R1 to flow out to ground and an opposite phase is created highly accurately; and it is allowed to flow to the ground directly or via a resistor R2. Thus, almost all of the modulated current flowing in a ground line S1 is canceled. The modulated voltage, generated in the power source circuit, is reduced by suppressing the modulated current flowing in power source lines (S2, S3), and the modulated voltage, which is generated in an internal circuit due to self-modulated current, is reduced by maintaining the impedance of a current supply source inside the amplifier circuit at a very low level.  <P>COPYRIGHT: (C)2004,JPO
