Title: Integrated circuit physically unclonable function

An integrated circuit (IC) based physically unclonable function (PUF) that comprises a common source amplifier for generating PUF output voltages, a unity gain, negative feedback operational amplifier for generating bias voltages, a voltage regulator and a bit exclusion circuit that excludes unstable PUF bits. Compensation circuitry built into the IC-PUF provides a high power supply rejection ratio and enables highly reliable operation of the IC-PUF across varying input voltages and operating temperatures. The IC-PUF generates a uniformly random output bit stream by taking advantage of process variations that are inherent to the fabrication of (metal-oxide semiconductor) MOS transistors.
