differential to single ended v/I converter

[scoobydoo]

Hey I´m looking for a fast differential to single ended V/I converter circuit.
where could I find information about it?
I looked through several books but could not find anything.

maybe i should explain with more detail.
i want to get in with a differential input voltage and get an single ended output current. with that output current i want to controll a delay line. therefor the dependence from input voltage to output current should be as linear as possible.

You should specify if you need a source, sink or floating output current. Find here a comprehensive application note on how to make current sources / converters: View attachment current_sources_BB_AB-165.pdf

oh yes. thanks for asking. i need a current source at the output.
