View attachment Volt to current.docHi, I am attaching a image for volt to current converter. I found it on some old thread here only.It looks like howland circuit with push-pull amplifier. My question: opamp o/p going to base of transistors. Emitter are shorted and we take output from there. Whether 390 ohm resistor which is actually connecting both base and emitters are correct in the diagram?
Here is my image URL or see the attached doc file

Thanks in advanced..I desperately need to build a bidirectional current source independent of load resistance.
