A new time-domain model for the slewing behavior of two stage opamps is presented. This model includes the effects of the load capacitance, compensation capacitance, device sizes and the nonlinear behavior of the transistors during the slewing period. This model improves on the commonly used constant current models and allows for more predictable designs. The model shows good agreement with simulations. Circuit design results using the traditional and new improved models are presented.
