150Worst case analysis is used to identify the most critical components that will affect circuit performance. Initially, a sensitivity analysis is run on each individual component that has a tolerance assigned. The component value is effectively pushed towards both of its tolerance limits by a small percentage of its value to see which limit would have a greater effect on the worst case output. A worst case analysis is then performed by setting all the component values to their end tolerance limits which gave an indication of the worst case results. In order to reduce the number ...
