Almost but not quite. Tie the VEA output directly to the CEA. You know the
sensitivity of the CEA so all you have to do is implement a local clamp
around the VEA so it cannot demand more than the current setpoint.

Is there a standard way of doing this? I can think of some, but none
seem to be very elegant. I'm trying to not require another op-amp. I
have 2 more which are being used elsewhere.
