Abstract: A burst mode receiving apparatus having an offset compensating function and a data recovery method thereof, including an intermediate value detector to detect and output an intermediate value of an input signal input from an outside source in response to a switching control signal; an amplifier to amplify and output a difference between the input signal and a reference value; an offset compensator to generate a compensation signal having a level varied corresponding to the amplified result input from the amplifier and a compensation control signal; a summing portion to add the compensation signal and the intermediate value to output the added result as the reference value to the amplifier; and a controller to generate the switching control signal and the compensation control signal corresponding to a result obtained by analyzing the amplified result input from the amplifier and a reset signal input from the outside source.
