Activity-monitoring completion-detection (AMCD): a new approach to achieve self-timing

The feasibility of a new method called AMCD to achieve completion-detection for self-timed circuits has been demonstrated. The major advantage of the proposed method is that data dependent delays of CLs can be exploited whilst imposing only marginal repercussions on the CL itself. An analogue simulation of a 4×4 bit multiplier using models of a commercially available CMOS process has demonstrated the practicality of the approach. The results obtained clearly demonstrate the benefits of the method
