Description

technical field [0001] The invention relates to the field of chip near-threshold technology, in particular to a low-complexity near-threshold XOR unit. Background technique [0002] With the rise of application fields such as the Internet of Things, medical electronics, and intelligent monitoring, many extremely low-power application scenarios have emerged. The near-threshold technology is the most effective technology to realize the extremely low power consumption of the chip, which can reduce the power consumption of the chip by an order of magnitude, and has attracted extensive attention and research in the past ten years. Although the near-threshold technology is effective, it also brings severe challenges, such as performance degradation, reduced stability, and process sensitivity. [0003] In order to improve the circuit stability in the near-threshold state, it is often necessary to add some auxiliary circuits on the basis of the traditional structure. Although the ...
