A Study of Tuning for Continuous-Time Filters Using Macromodels
The ability to simulate tuning of integrated continuous-time filters in a real circuit context is a difficult but increasingly important task as such filters are becoming more widespread. This paper describes such a study using macromodels. 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 was demonstrated by the good agreement between macromodel and full transistor simulations. This paper validates that a significant increase in simulation speed can be achieved.
