Hi,

I'm new here, so tell me if you need more information.

I have problems to understand everything, when I'm going from single-ended to fully-differential circuits. I added a simple schematic as pictures, there are two inverting amplifiers on it and the the other picture is the ac-response of both. The resistors are 1k Ohm and the gainbandwith of both amplifiers is 1Ghz. The amplifiers are idle amplifiers written in VerilogA.

Now my question, why is the 3dB-corner fully-differential double to the 3dB-corner single ended?

Thanks,
Rudolf
