A differential evolution (DE)-based adaptation algorithm has been proposed in lieu of the existing genetic algorithm (GA) to reduce the computation time. A three-stage CTLE having 12 tuning parameters has been adapted with the DE algorithm to compensate for a channel loss of 20 dB at the Nyquist frequency of 50 Gb/s for non-return-to-zero (NRZ) and pulse amplitude modulation 4 (PAM-4) level signaling. Simulations show that DE-based adaptation is almost 2 � faster than GA-based adaptation algorithm for a given population size. � 2011-2012 IEEE.enAdaptation; continuous-time linear equalizer (CTLE); differential evolution (DE); genetic algorithm (GA); serial linksArticle
