[sdiy] current conveyor?

[David G Dixon]

Do any gurus here know of a circuit to convey a current from a virtual
ground point to another point at any voltage?  Essentially, I'm trying to
feed the current output from a 2164 (which must feed to virtual ground) to
an integrator with a voltage of -5V at its + input.  I want to convey the
2164's current precisely to that integrator.  I know I can convert the
current to a voltage, and then send it back to the integrator through
another resistor while also summing in a current from -10V through the same
resistor.  However, notwithstanding the fact that this arrangement will also
invert my current, input offset voltages are going to wreak havoc with
precision.  I guess what I'm asking is, is there any way to do this without
first converting the current to a voltage?  The current needs to be able to
flow in both directions.  Any help most appreciated.
