The present disclosure provides a fries box-packing machine, relating to the technical field of food packaging. The fries box-packing machine includes a frame body, a box storage component, and a box-taking mechanism. The box-taking mechanism is arranged on the upper mounting plate, and the box-taking mechanism is configured to sequentially move the paper box of the box storage component below the upper mounting plate. The lifting mechanism of the box-taking mechanism of the fries box-packing machine provided by the present disclosure can elevate the rotating mounting frame, thereby adjusting the height of the suction cup assembly. This allows the suction cup assembly to move the paper box from the upper end of the upper mounting plate to the lower end of the upper mounting plate. When the suction cup assembly attaches to the paper box, the lifting mechanism separates the paper box from the box storage component.

A PUF circuit based on the threshold loss of MOSFETs comprises N stages of delay units and an arbiter. Each stage of delay unit comprises six inverters and four MOS transistors, wherein the four MOS transistors are all PMOS transistors or NMOS transistors. Each path in each stage of delay unit uses only one PMOS or NMOS transistor and does not use a transmission gate formed by a PMOS transistor and an NMOS transistor. Therefore, it reduces hardware cost. Each MOS transistor on the transmission path has a threshold loss, PMOS and NMOS transistors in a third inverter and a sixth inverter are in an on-state, and output terminals of the third inverter and the sixth inverter will be charged to a high level or discharged to a low level, thus greatly increasing a delay difference between two square signals and enhancing randomness.
