AC Transfer Characteristic for Differential Input and Output

Lane Boyd

Hello,

Using TINA, is there a way to measure the AC transfer characteristic for a circuit with a differential input and differential output? My circuit is below.

Thanks,

Lane

Hi Lane,

One way to do this is to split the signal at the input either using a transformer or voltage controlled sources. I've used a transformer with a center tap as show below to split the signal and then I measure the differential output by using a voltage meter connected across the output resistor. I also attached my TINA test bench.

You can run your AC Transfer Characteristic analysis from 1 to 10k and you should see the effect of the 2nd order low pass.

Hope this helps,

Marcos
