In a pseudo-differential power amplifier, often capacitive neutralization is used to to neutralize the gate-drain capacitance of the transistors. This enhances gain and differential stability, i.e., the stability we looked at above when the inputs are driven with a differential signal.

The signal at the gates can have a common-mode component, however, meaning that it is the same on both sides. This can occur because of the balun not being balanced or common-mode noise. Hence, common-mode stability needs to be assessed.
