Abstract: The network filtering circuit includes a cable side for connection with a network cable, a physical side for connection with a mother board, and a plurality of transmission channels connected between the cable side and the physical side. Each of the transmission channels includes an autotransformer with a center tap sequentially connected by a capacitor and a resistor in series connection wherein a power supply is connected to a position of a circuit between the capacitor and the center tap, and another capacitor having a higher capacitance is linked to the resistor opposite to the capacitor. All transmission channels share the same capacitor having the higher capacitance to a same ground node.
