A low distortion inverting amplification circuit is provided to obtain outputs having low distortions by utilizing an inversion feedback amplification algorithm in an operational amplification circuit. An inverting amplification circuit(300), which includes an inverting amplifier having a finite DC(Direct Current) gain, outputs an amplification result on at least one input signal based on an inverting feedback scheme. The inverting amplification circuit includes an operational amplifier. An inverting terminal of the operational amplifier receives a voltage(Vx) of an inverting terminal of the inverting amplifier and a non-inverting terminal thereof receives a reference voltage(VREF). According to the reception, the operational amplifier outputs an amplification result based on a finite DC gain to a non-inverting terminal of the inverting amplifier. |
