what's the design consideration for Cout

Aug 08, 2008 2 Replies

Here is the question: if I want to switch AC and (AC+DC) signal from a high speed op-amp, the output load is 50 ohm, I want to put a capacitor between op-amp output and the 49.9 ohm resistor, how to choose the capacitance?



thanks.


What is the maximum frequency?

That is all.

What is the minimum & maximum frequency? If you want DC you can't use a capacitor. In that case, use a split +/- supply and reference the op amp to ground.
