Novel Concept Dynamic Feedback MCML Technique for High-Speed and High-Gain MCML type D-Flip Flop

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, I propose the novel Dynamic Feedback (DF-) MCML technique for high-speed and high-gain MCML type D-Flip Flop (D-F/F).
The concept of the proposed DF-MCML technique is as follows; the output node signal is feedbacked to the input node in Sampling-Mode, and the output node is opened from the input node in Holding-Mode. It is shown by analytic theory that by this dynamic feedback sequence, both stability and sensibility of D-F/F in Sampling-Mode is exponentially improved, and the gain of D-F/F in Holding-Mode is drastically increased.
Finally, I have numerically investigated the circuit performance of the novel DF-MCML type D-F/F in comparison with the conventional MCML type D-F/F by using P-Spice simulator. The maximum operation frequency of 180nm DF-MCML type D-F/F reaches over 20GHz that is 2 times than the conventional MCML type D-F/F.
It is made clear that the proposed novel Dynamic Feedback MCML technique is suitable for over 10GHz high-speed and high-gain Si ULSIs.
