Different settling time curves can be produced by modifying the goal functions for different defined levels.
Figure 3 shows the curves for the settling time to 20 mV, 10 mV, and 5 mV, by setting the defined level at
1.02, 1.01, and 1.005, respectively. Note that both the marked point expression and the LEVEL function
are modified for each distinct defined level. In Figure 3, each settling time curve has been defined as a
macro expression. For instance:
settle_10mV = s1(v(2)) + s2(v(2)) + s3(v(2))
To smooth the curves even further, a more appropriate function could be defined using goal functions.
