Abstract

An electromagnetic interference suppression circuit, a driving method thereof, and an electronic apparatus are provided. In the electromagnetic interference suppression circuit, a signal generating sub-circuit may generate a plurality of parallel target sequence signals, each with a period greater than a period threshold and a quantity of target sequence signals greater than a quantity threshold; and a frequency generating sub-circuit may output a frequency-jittered drive signal, for driving a switch mode power supply to operate, to the switch mode power supply under the control of the plurality of parallel target sequence signals.
