Hi
I need help with a relatively simple Analog design problem....
I have a differential signal that I am 'tapping' into. (It goes to another system...so input impedance of my circuit must be high > 100kR).
The characteristics of the signal are:
Amplitude can be 1vpp to 5vpp
Offset is always positive (and the signal never goes negative) and can be from 0 to about 5v
The signal can be sine or square wave and neither of the two signal wires are ground biased.
Output requirements are simply ground referenced signal, preferably square wave.
I thought of using a simple diff amp, and in simulator it works, but in practice not at all.
