Abstract :
In this paper, design parameters of a current reference circuit are automatically generated according to specific design constraints. These constraints can be minimal consumption current or minimal temperature coefficients. This methodology is based on a current reference mathematical model. This model is generated thanks to a dasiaDesign Of Experimentpsila (DOE) technique. The DOE technique takes as input electrical simulation results of a current reference circuit for different component geometries. DOE generates polynomial equations of the current reference output IREF, the consumption current ISUNK, the temperature dependency factor betaT and the supply voltage dependency factor betaV. Using these equations and according to a given design specification (IREF, ISUNK, betaT or betaV), the most suitable design parameter values are generated.
