Online circuit simulator & schematic editor - CircuitLab
CircuitLab provides online, in-browser tools for schematic capture and circuit simulation. These tools allow students, hobbyists, and professional engineers to design and analyze analog and digital systems before ever building a prototype.

A transient simulation is analogous to using an oscilloscope to make observations about a circuit -- observing the full, non-linear behavior over a wide range of time scales. Frequency-Domain Simulation Frequency Simulation does a small signal analysis of your circuit. The input can be any voltage source or current source.

Simulation Troubleshooting CircuitLab is a very flexible tool with a wide range of applications. As with any general purpose user-programmable software, it is possible to get into a broken state where the simulator is unable to find a solution to your circuit, or sometimes to …

CircuitLab's advanced simulation engine makes it easy to find the small-signal impedances looking into any terminal. In fact, it makes it incredibly easy to see how these parameters vary when we change the circuit a bit. Click to focus the simulation settings window, and click to check the Sweep Parameter box.

Click and drag the Time Controlled Switch to break the wire between V1 and R1: We've now completed the circuit. Switch to simulation mode by clicking Simulate at the bottom of the window: We'd like to see the step response, so click Time Domain in the simulation settings panel: To run the simulation, we need to tell the simulator what to plot.

The DC sweep plot shows the behavior of the circuit with input voltage on the x-axis and output voltage on the y-axis. Clearly this is an inverting amplifier with a gain of -10. Now, let's see how the circuit behaves in the time domain. Click Hide on the plot window, and then open the Time Domain panel on the simulation settings window.
