Why is my "common gate amplifier" introducing a zero when it shouldn't be introducing one as per theory?

I am trying to simulate a cascode circuit followed by a source follower in LTSpice and observe its frequency response. I added a 100GH inductor to serve as negative feedback only for DC, i.e., the ...
