Design and Simulation of a Group Delay Equalizer Circuit

A design and simulation analysis method with genetic algorithm for the group delay of the ADC system balanced circuits is introduced in this paper. With the discussion of characteristics of linear phase of the system, genetic algorithm technology was introduced into the analysis and calculation of group delay equalization circuit of an anti-aliasing filter with given structure and parameters, genetic algorithm is applied to optimize the design of zero poles of the circuit transfer function with satisfied results. With the optimized zero poles intuitive and stable two-second-order structure is used for integration of circuits, followed by the confirmation of reliability of the circuit by simulation and sensitivity analysis. The results show that the circuit design optimization through genetic algorithms in engineering is of great feasibility and practical value in circuit optimization process. MATLAB tools were used in the simulation design and analysis.
