Op-Amp Circuits Simulated Three Ways Scroll through the screenshots below to learn how to analyze op-amp circuits at DC, in the time domain, and in the frequency domain. Press / (forward slash) to begin a toolbox search, and type "op": There are two op-amp models in CircuitLab, one with and one without voltage rails. The simpler "without" version simulates faster if you're not concerned with ...
