Hello people,

I have a strange problem. I just designed a basic current to voltage converter amplifier using a simple op-amp. My Input is coming from an AC Current source. When I label just next to the input as Port1, and want to see the output of my Current Input. It is giving me a voltage in a time domain signal.

The output of a AC current source should be a CURRENT in the time domain, not a voltage.

Please help, in how to obtain current signal in the simulation

Thanks alot

Use Transient simulation, not an AC simulation.

Add current probes where you wish to measure the current in your schematic. The current through those probes will be saved in the dataset as current vs time when you run a Transient simulation.

Thank you,
Now i will start using transient simulations

Thanks alot once again

Hello,

I just tried using the Transient Simulation, but i get an error message in my terminal window of my Unix machine.
The error message is
"ERROR AEL0304 (get) operand: wrong type of parameter"

PLease help!!!

Thank you
