Abstract: The present invention relates to a circuit of filtering a noise and amplifying a signal for an optical detection module. The present invention is able to: optimally design a circuit which is able to prevent the saturation of an optical detector which is caused by sunlight and an outside noise (DC and AC elements); increase sensibility which is a system performance and satisfy a dynamic range by amplifying only a signal to detect through a signal process; design a circuit with an excellent amplification factor which is strong against noise features and a harmonic wave distortion signal; prevent damage to an integrated circuit (IC) element which is caused by ringing signal amplification; and miniaturize the circuit.
