Abstract
A derivative receiver includes a differentiator configured to differentiate an input signal; a comparator configured to produce a comparison signal by comparing a derivative signal produced using an output from the differentiator with a threshold voltage; and a pattern detecting equalizer configured to output a data signal by sampling an equalization signal generated by adjusting a level of the comparison signal. The level of the comparison signal is adjusted according to a past value of the data signal.
