Analyzing Circuits with Parametric Sweeps in LTSpice

Understanding Parametric Analysis

Parametric analysis is a powerful technique in circuit simulation that allows you to analyze the behavior of a circuit while varying one or more parameters. This can be useful for exploring the effects of different component values, temperature, or other factors on the circuit's performance.

Using the STEP Command for Parametric Sweeps

In LTSpice, the STEP command is used to specify a parametric sweep. The syntax of the STEP command is as follows:

``` .STEP ```

For example, the following command would sweep the independent current source I1 from 10u to 100u in step increments of 10u:

``` .STEP I1 10u 100u 10u ```

The .STEP command is particularly useful for sweeping a parameter across a range of values in a single simulation run.
