Abstract
An output signal can be free of any noise component generated from an amplifier disposed in a path, without degradation of the S/N ratio of the output signal. An amplifier includes: a first amplifier that is connected to an input node and generates a first intermediate signal; a feedback resistor that enables feedback of the first intermediate signal to the input node; an attenuator that receives the first intermediate signal and generates a second intermediate signal; a second amplifier that is connected to the input node and generates a third intermediate signal; a third amplifier that is connected to the input node and generates a fourth intermediate signal; and an adder that generates an output signal, using the second intermediate signal, the third intermediate signal, and the fourth intermediate signal.
