A new method of modeling coaxial cable frequency response with genetic algorithm was introduced. A system-level multi-stages adaptive equalizer model with QFB block was generated and tested with multiple cable models, pathological PRBS-23 data with data rate 1.5 GHz was used. This thesis also provided analysis of influences on output by using different parameters in simulations. Two adaptive equalizer circuits with different pre-amplifiers were implemented in GPDK 45 nm CMOS technology. Related simulations about adaptive ability, single stage compensation ability, and cascade stages compensation ability were completed. A tradeoff between output eye height and peak-to-peak jitter was discussed based on different simulations. Future work will be digital control circuit implementation, entire circuit fabrication, and testing.
