Hello! I have an ABM part in PSpice. That means, I have a part that has two voltage inputs and with mathematical equations it generates a current output. I want to convert this current output to voltage so it can enter to another ABM part's voltage input. Is there such converter in PSpice? And if yes, which one? Thank you!
"I want to convert this current output to voltage"
I think, it is not necessary to use an opamp as a transresistance amplifier.
A simpler solution is to use a suitable resistor Rx that converts the current into a voltage Vx and to use the ABM model "Gain" for amplification (with a factor G) and to provide a zero output resistance.
Example: I=1mA and Rx=1kohm result in Vx=1V. Multiply this voltage with any desired gain value G.

Yes, a resistor (as suggested by Lutz von Wangenheim) would do the job and, if you are concerning about loading and impedances, use an opamp to copy the input voltage to the output. The resistor goes to ground and the op-amp has a short from the output to the inverting input.

You're looking for a current controlled voltage source, this is already included in Spice as "H" source. You won't have to build anything, it's already included.
See the PDF above for a small explanation
Mr Victor Sluiter has given a suitable answer. What you want is a current controlled voltage source which is already included Pspice.
