Message Date From Subject 5436 2010-11-19 08:11:55 Alberto I2PHD Differential to Single-Ended I am trying to design a differential to single-ended circuit, to be used in an active antenna (a mega loop) project.
I received an advice about using a Norton current mirror in a differential amplifier. I tried to simulate that with
PSpice, but the results were horrible... can please somebody shed some light on the errors I made in the

Have you been looking into this one:
If it is not what you need, it still is a good read on the subject!

made with LM833 operational amps. Set for ~60 dB of gain.
