  1. What kinds of noise sources do you consider in your model?
  2. Which noise cancelling do you choose for your study? Or you combine multiple techniques you mentioned? Reason?

Thanks for your question! I choose to consider thermal noise as the noise source, which is typical in LNA design. Initially, I focused on the common-gate common-source topology to study and found out during the derivations that this positive feedback published in ISSCC2022 can potentially be a new canceling topology and cancel without an auxiliary path. I found this result interesting so I tried to do more on this.
