Hi,

How do I do a current analysis?

I tried Transient analysis

Esme,

What do you mean by a current analysis? What current are you trying to see? What are you going to use the information for?

If this is a circuit that will be operating using a time based waveform (I do not know as VG1 could simply be a step or ramp), you would want to do a transient analysis and the currents shown would be waveforms. If you want to see what the circuit consumes at T=0, you could do a DC analysis, giving you the current before the time varying starts (operating point).

I'm actually using a current generator so I think I should use AC analysis?

How do I switch the y-axis from gain dB to current?

Thanks

Esme,

If you are using a current generator, I would probably use Transient analysis. I assume that you want to see the currents and voltages with respect to time in your circuit. AC analysis is going to provide you the circuit response in the frequency domain, not the time domain.

The type of simulation analysis you should be running depends on what you are trying to learn about the circuit.
