%X To improve the simulation accuracy of SIMULINK,a novel inclusive beha vior model of an integrator is proposed that introduces the effects of different circuit nonidealities of a switched-capacitor sigma-delta modulator into SIMULIK simulation.The nonlinear DC gain and nonlinear settling process are introduced into the op-amp module.The signal-dependent charge injection and nonlinear resistance are introduced into the switch module.In addition,the noise source in cluding flicker and thermal noise is introduc...
