Abstract :
In this paper a new method for analog circuit sizing with respect to manufacturing and operating tolerances is presented. Two types of robustness objectives are presented, i.e. parameter distances for the nominal design and worst case distances for the design centering. Moreover, the generalized boundary curve is presented as a method to determine a parameter correction within an iterative trust region algorithm. Results show that a significant reduction in computational costs is achieved using the presented robustness objectives and generalized boundary curve
