1. bucking circuit that suppresses the high speed circuit electromagnetic interference, this bucking circuit is characterised in that and comprises:

  • A phase shifter (phase shifter) is used for the signal phase shift;

    A high-speed signal circuit, described circuit are the circuit of single-ended signal (Single-ended signal);

    AndA differential wave circuit, described circuit are via glitch (DummySignal) circuit after the above-mentioned phase shifter phase shift, and the contiguous described high-speed signal circuit of this differential wave circuit, in order to produce magnetic field cancellation and field coupled.
