A symbolic macromodel for slew and settling characterization of fully differential switched-capacitor (SC) integrators is proposed in this work. This model is intended for fast behavioral simulation of data converters in the time-domain. The main advantages of the proposed model are: 1) it can be created automatically without the need of running a transient simulation; 2) it is fully composed of circuit elements that can be simulated by SPICE or MATLAB; 3) it is created in symbolic form so that adjustment of the transistor-level circuit is directly reflected in the macromodel without the need of remodeling. The proposed modeling methodology is validated by applying to SC integrators implemented by two different operational amplifiers. The step response waveforms of the integrator model have good agreement to the transistor-level simulation results with a speedup of about 20x.
