It is a headscratchingly bad idea to put op-amps in week 2 of course #1. I can’t even remember for sure if we did them in the first course, but if so, it was at the very end, after you already know how to do algebraic working-out of values in a circuit. From there, they give a couple algebraic rules to figure out what an op-amp circuit does. And a key point that is usually glossed over is: op-amps are basically useless when not in a feedback configuration, and some of the analysis rules are based on already assuming the op-amp is in a feedback configuration. |
