Can't find old thread.....

I am looking for and old thread where a 3 transistor I/V converter were shown.....I think it was a guy from Poland?

Very simple and with a 470R resistor from input to output....

I have searched for days now.....

No, none of them, sorry.

It was a 3 transistor version, with feedback from output to input (470R). A kind of compound transistor with feedback.

The output had a 470R resistor to Vee and someone suggested to replace it with a current source....

The thread were only with few answers, perhaps 5-7 replies...

YES!!

Thank you very much......how did you find i?

Sharp aye and stady hand ... just type a three transistor i/v stage in search function and sail a bit thru results
