LTSpice noob question

Nov 30, 2010 2 Replies

I want to plot the transfer characteristic of a CMOS inverter, with input voltage on the horizontal axis and output voltage on the vertical axis. If I do a voltage sweep I guess I could get a graph that looks like the transfer curve, but it will have units of time on the horizontal axis. There must be some way to get a proper graph of output voltage versus input voltage. How do you do that in LTSpice?

Left click on horizontal axis and change "time" to your input voltage.
