Hi, for a common gate amplifier circuit what determines the voltage swing? I've attached an image of a circuit.

Would the voltage swing be across Rd?

 

The voltage swing, unless otherwise specified, normally refers to whatever is considered the "output". I would image that in this case it is referring to the voltage across R5, which I'm assuming is an AC-coupled load.
