Abstract:
Disclosed is an optical communication receiver capable of compensating a DC offset while preventing an input load effect. The optical communication receiver includes an optical signal detector; an amplifier inputted with a photocurrent outputted from the optical signal detector; and a DC offset compensation unit provided therein with a third transistor and a fifth transistor which are connected in series to each other to prevent an input load effect, wherein the DC offset compensation unit compensates a DC offset by outputting at least a portion of DC current inputted to the amplifier to ground through the third transistor and the fifth transistor when the photocurrent is an over current more than a predetermined set value.
