Description

technical field [0001] The application relates to the field of integrated circuits, in particular to a logic operation circuit, a differential amplifier circuit and electronic equipment. Background technique [0002] In recent years, with the rapid development of semiconductor integrated circuits, the security problems caused by the loopholes of integrated circuits have become more and more significant. Side channel attack, also known as side channel attack, its core idea is to analyze plaintext information or key information by obtaining various leaked information generated during hardware operation. The various leakage information generated during hardware operation mainly includes variables such as power consumption, electromagnetic radiation, or temperature when the internal level of the chip is flipped. By analyzing these variables, the data information inside the chip can be captured. With the development of mobile payment, more and more confidential data are built on...
