•Set V
IN
with a step amplitude of 1.4V and a center voltage of 2.5V. (i.e. V
IN
starts
0.7V below center and ends 0.7V above center)
• The output step response is shown in Figure 2-16. It is a signal with a step
amplitude of 4.2V and a center voltage of 2.5V. (i.e. V
OUT
starts 2.1V above center
and ends 2.1V below center)
