What is the nested dc sweep?

A nested DC sweep is a simulation technique used in circuit analysis to systematically vary multiple parameters or sources in a circuit while observing the response of other circuit elements. This method involves performing a DC sweep for one variable while simultaneously sweeping one or more additional variables, allowing for a comprehensive examination of how changes in parameters affect circuit behavior. It is particularly useful for analyzing complex circuits where the interaction of multiple variables is crucial for understanding performance, stability, and other characteristics.
