Patent ID: 7375983

Claim:
A circuit board for reducing crosstalk of signals, the circuit board comprising: a first surface and a second surface; a plurality of layers aligned with respect to each other in a stacked arrangement between the first surface and the second surface, wherein a first group of the layers is located closer to the first surface than the second surface of the circuit board and a second group of the layers is located closer to the second surface than the first surface of the circuit board; a semiconductor control component arranged on the first surface of the circuit board; a pair of first contact terminals arranged on the first surface of the circuit board, wherein one of the first contact terminals is configured to apply a first input signal and the other of the first contact terminals is configured to generate a first output signal; a pair of second contact terminals arranged on the second surface of the circuit board, wherein one of the second contact terminals is configured to apply a second input signal and the other of the second contact terminals is configured to generate a second output signal; a pair of first conductor tracks, wherein one of the first conductor tracks is configured to transmit the first input signal from the one of the first contact terminals to the semiconductor control component and the other of the first conductor tracks is configured to transmit the first output signal from the semiconductor control component to the other of the first contact terminals; a pair of second conductor tracks, wherein one of the second conductor tracks is configured to transmit the second input signal from the one of the second contact terminals to the semiconductor control component and the other of the second conductor tracks is configured to transmit the second output signal from the semiconductor control component to the other of the second contact terminals; wherein the first conductor tracks run within at least one of the layers of the first group of the layers, and the second conductor tracks run within at least one of the layers of the second group of the layers.
