A Comparison of Digital Droop Detection Techniques in ASAP7 FinFET

Abstract

This report compares current techniques for digital supply droop detection. While there are many droop detection circuits in use, they have been thus far studied in isolation; it is not clear what the design merits and trade-offs of different topologies are. This project presents design methodologies for two single-cycle digital droop detectors, which are used to design and compare droop detector sensitivity and selectivity for two representative example specifications in ASAP7.
