Abstract :
Simulation of tuning of integrated continuous-time filters in a real circuit context, using macromodels, is described. The macromodels include circuit nonlinearities and bias-dependent parameters which are required for a study of tuning. The success in identifying and modeling the important parameters is demonstrated by the good agreement between macromodel and full transistor simulations. It is shown that a significant increase in simulation speed can be achieved
