Provided are a receiving module and a receiver having the same. The receiving modules includes: a comparing and detecting means for comparing a current bit of a received signal having a continuous waveform to a previous bit thereof and detecting a difference between the current bit and the previous bit; an amplifying means for amplifying the difference detected by the comparing and detecting means; and a sampling means for sampling a waveform of the received signal amplified by the amplifying means to output valid data.
