TINA-TI: Setting CCCS Current Amplification gain as the input for AC Analysis?

Jim Schwendeman

Part Number: TINA-TI

Howdy forum,

I'm simulating a reverse-biased photodiode in TINA, and using a CCCS to represent photodiode current. I'd like to look at the circuit response as a function of the CCCS Current Amplification Gain, is there a way to do this?

I have a workaround where I have a parallel VCCS that I command with a voltage generator, but my circuit would be more representative if I could directly vary the CCCS Current Amplification Gain.

Thoughts?

Much appreciated!

Thanks Leonard,

After looking at the Controlled Source Wizard a bit more, I found a cool solution. You can make a multi-input current source, and then define the equation to modify the gain based off the input voltage. That voltage source can then be selected as the input for AC Analysis!
