In Baker's book he introduces an edge triggered D flip-flop using transmission gates:
**broken link removed**
However I can't find much information about the advantages and disadvantages of this design compared to the regular NAND implementation. I noticed from simulations that the tgate version worked at higher frequencies and used less power. Does the tgate version have more propagation delay or something? Or maybe I just sized the NAND version wrong (just used the same drive strengths for every gate).
edit: Sorry, should have specified that my question is in the context of designing standard cells
