Struggling w. a Single Supply Integrator
<< < (4/4)
rstofer:
Maybe it's complicated like Maxim says in this white paper:

I was thinking about using modern single rail op amps for another analog computer.  I think I'll give that a pass.

You're using the V2 node for a supply voltage while V2 is actually a voltage source, not a node name...  Not sure what Spice will do in this case, but quite probably not anything reasonable.  (The reasonable behavior IMO would be to produce an error.)

rstofer:
Right, use an OUTPUT port where you generate Vref and an INPUT port at the op amp.  The port icon is on the toolbar between Gnd and Resistor.

Ditto...I simulated it with ports configured properly and it works fine.
