Optical receiver and data communication apparatus comprising same

Image Number 3 for United States Patent #7509059.

An optical receiver is capable of minimizing fluctuations in the pulse width of an electrical signal rendered by converting an optical signal of broad-range illumination. The optical receiver includes a light-receiving element that receives an optical signal and converts the optical signal into a current; a bypass element through which a portion of the current of the light-receiving element flows; an impedance element that detects the remaining portion of the current of the light-receiving element and converts the remaining portion into a voltage signal; a voltage separation element interposed between the impedance element and the light-receiving element that separates the voltages on both sides thereof; and an automatic gain control (AGC) circuit to which the voltage signal from the impedance element is inputted and that controls the current flowing to the bypass element in accordance with the voltage signal.
