[sdiy] LTspice - exponential voltage curve

[Justin Owen]

Hello,

Taking my first few steps with LTspice. I'm simulating a simple Linear to Exponential converter running a VCA. I'm scoping/probing the sine wave output of the VCA.

For the linear current source I could run a scope of the linear CV input as it ramped from 0V to 2.5V and graph that against the VCA output to check it's linearity - now I'd like to have a similar exponential voltage source to graph the VCA output against using the Lin/Exp converter.

How would I do that in LTspice?

Got sort of close with an arbitrary voltage source reading of a linear source.

Thanks!
