This paper presents an ultra-low power and lower area, sequential physically unclonable function (PUF) circuit for Internet-of-Things (IoT). The proposed PUF is used to generate a 16 bit secret key array and uses a current-mode based differential bit cell architecture to exploit the inherent device mismatch. The proposed PUF design has an energy efficiency of 7.5fJ/bit and a native instability of 0.6875%.
