The method of maximizing process variation of the PUF device includes: modeling a physically unclonable function (PUF) device, comprising a plurality of PUF cells, selecting the size of transistors in the PUF device to be smaller than a predetermined size defined according to a design rule check (DRC) and generate maximum variations among the plurality of PUF cells, varying the material of the PUF device, and driving the PUF device with a predetermined voltage. The physically unclonable device includes: a plurality of PUF cells, configured to generate an output. Each of the plurality of PUF cells includes a harvester circuit, configured to generate a bit line and a complementary bit line. The harvester circuit is selected to be smaller than a predetermined size defined according to a design rule check (DRC) and generate maximum variations among the plurality of PUF cells; and a sense amplifier having a plurality of transistors configured to receive a first input signal and a second input signal from the harvester circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Physical unclonable device and method of maximizing existing process variation for a physically unclonable device","description":"A physically unclonable function (PUF) device and a method for maximizing existing process variation for a physically unclonable device are provided.
