Hi people,

I was reading something about a two-stage amplifier and at some point, they say the following:

"Due to feedforward path with no inversion from the first stage output to the op-amp output provided by the compensation capacitor at high frequencies, the op-amp performance shows the following (...)"

What I want to ask is what do they mean by due to feedforward path? What is this about this conventional two-stage amplifier? And what they mean by "with no inversion"? I don't understand. Any help will be appreciated.

Regards.

The compensation capacitor (Cc) is connected as a Miller capacitor between the output and the input of the 2nd stage. We use Cc for pole splitting, to improve stability.
This is not just a feedback from the output to the input of the 2nd stage, also the 1st stage has a feedforward path through Cc from the input to the output of the 2nd stage.
The feedforward path causes right half-plane zero in the open-loop transfer function, which is not good for stability.
