So far so good for DC, but we still need to know the characteristic for fast changing sensor output – what’s the waveform going to be. Let us replace Vsensor from DC 1V to Step 1V by double click on the source and configure the output to be 1V Step voltage with 2ms delay:
To ease subsequent examples about simulation, change some of the op amp settings by double click on it, change as below:
To plot the waveform, insert a probe at the output of buffer (short cut “B”)
Then choose Transient analysis:
And you would get nice waveform as shown below:
So far so good - but is it too good to be true?
