[OFFSET CIRCUIT FOR SUPRESSING ELECTROMAGNETIC INTERFERENCE AND OPERATION METHOD THEREOF] |
摘要 |
A circuit for suppressing electromagnetic interference (EMI) and operation method thereof is provided. Interfering signals captured or coupled from the motherboard are transmitted to the phase-shifter for shifting the phase of the signals. The interfering signals with phase shifted are outputted and coupled to the ground layer or the power-supply layer to offset EMI noise thereof. Since merely additional space for the phase shifter is reserved on the motherboard, EMI effect is eliminated and time and cost for rerouting the circuit is thus reduced.
