The demand for high-speed, low-power communication circuits has dramatically grown over the past few years. Potential markets from powerful personal communicators to wireless ATM systems have stimulated great effort in reducing the supply voltage and power dissipation of gigahertz circuits. In this respect, deep submicron CMOS technologies have become(More)
This paper compares two types of physical unclonable function (PUF) circuits in terms of reliability, mismatch-based PUF vs. physical-based PUF. Most previous PUF circuits utilize device mismatches for generating random responses. Although they have sufficient random features, there is a reliability issue that some portions of bits are changed over time(More)
