ABSTRACT:
A feedback amplifier includes an input terminal where an input voltage is detected from an input current; an amplifier circuit which amplifies the input voltage to generate an output signal; a first output terminal from which the output signal is outputted; and a feedback circuit. The feedback circuit includes a feedback resistor connected between the input terminal and the first output terminal; and a diode which connected in parallel to the feedback resistor. The output signal is feedback-controlled in response to the product of the input current and the impedance of the feedback circuit.
