Abstract

See full text

A FET pair based physically unclonable function (PUF) circuit with a constant common mode voltage and methods of use are disclosed. The circuit includes a first n-type field effect transistor (NFET) and a second NFET. The circuit also includes a first load resistor coupled to the first NFET by a first p-type field effect transistor (PFET) and a second load resistor coupled to the second NFET by a second PFET. The circuit further comprises a closed loop, wherein the closed loop creates a constant common mode voltage.
