The invention discloses an anti-electromagnetic interference method and device. Wherein, the method includes: detecting the interference noise of the target chip, wherein the frequency of the interference noise falls within the operating frequency band of the target chip; and adjusting the basic clock frequency of the target chip until the frequency of the interference noise moves out of the operating frequency band, wherein the The frequency is the product of the frequency of the interference module and the harmonic order, the interference module is a module that generates interference noise inside the target chip, and the frequency of the interference module is the frequency of the basic clock frequency of the target chip after frequency multiplication. The invention solves the technical problem of increasing the hardware cost caused by the related art adopting the shielding cover for the chip to solve the electromagnetic interference problem of the chip.
Description
technical field [0001] The invention relates to the field of electronics, in particular to an anti-electromagnetic interference method and device. Background technique [0002] With the rapid development of electronic technology, there are more and more types and quantities of electronic chips. Electronic chips consume current in normal working conditions, and different modules inside electronic chips will generate electromagnetic interference at different operating frequencies. Electromagnetic interference will generate radiation or conduction interference, which seriously affects the performance of electronic chips. In order to improve the performance of the electronic chip, it is necessary to eliminate the electromagnetic interference inside the electronic chip. The existing technology usually adopts adding a protective cover outside the electronic chip, changing the module layout, or using a filter to eliminate electromagnetic interference. However, the above method inc...
