Low Pass Filters

Physical Unclonable Functions (PUFs) are probabilistic circuit primitives that extract randomness from the physical characteristics of a device. PUFs are easy and simple to implement and its random nature makes its behavior hard to predict and model. Most existing PUF designs are based on variation at the chip level and can not be implemented in a printed circuit board (PCB). Therefore, these PUFs can not be used to protect against counterfeit PCBs in a distributed supply chain. In this work, we propose a novel PUF design based on resistor and capacitor variations for low pass filters (LoPUF). We demonstrate the setup in a protoboard for different resistor-capacitor pairs (RC pairs) for reliable low pass filter PUF. Because of process variations, the voltage will be different at the same cut-off frequency for our proposed PUF. Finally, the output of the filter is connected to an inverter to measure the pulse width and best suitable pulses are used for ID generation based on our algorithm.
