して負帰還信号を得る増幅手段と、該負帰還信号と上記
入力信号とを加算して上記増幅器の入力端子に印加する
手段とを有する増幅器において、上記増幅手段を交流分
のみ負帰還する負帰還増幅器により構成することにより
該負帰還増幅器の直流における増幅度を大としたことを
特徴とする増幅器。Amplifying means for amplifying the difference between the output signal of the amplifier and the input signal with an amplification factor of 1 to obtain a negative feedback signal; and means for adding the negative feedback signal and the input signal and applying the resultant to the input terminal of the amplifier. An amplifier characterized in that the amplification means is constituted by a negative feedback amplifier that provides negative feedback only for an alternating current component, thereby increasing the degree of amplification of the negative feedback amplifier for direct current.
