What is wideband amplifier? What is source degeneration?

The wideband amplifier will be used to supply power to integrated circuits, the operational amplifiers will have a load at their outputs. As the load resistance increases, the op-amp's output resistance becomes less dominant, specifically in the low-frequency range.

Source degeneration boosts the output impedance but decreases the usable output swing.
