Abstract: An exemplary embodiment of the present disclosure provides a physically unclonable function (PUF) cell capable of exhibiting a stable performance and showing an excellent repeatability while being less affected by environmental factors such as a noise, temperature, and bias voltage. The PUF cell generates an output value by combining a scheme of amplifying a threshold voltage difference and a scheme of amplifying an oscillation frequency difference. In an oscillator that generates oscillation signals of different frequencies, the frequency difference of the oscillation signals is amplified by alternately supplying bias voltages of different magnitudes generated by utilizing the threshold voltage difference to a plurality of stages in the oscillator.
