This is pretty neat! I think it's worth doing more analysis on the entropy cells separately from the entropy extractor. For example, the von Neumann extractor requires exchangeability of the input bits. Does this hold? In the setting where there is no phase noise from the entropy cells (and hence no entropy), does the TRNG give any output? Assuming some basic model (maybe measure this?) about gate delays, how much entropy should be generated by each entropy cell?
