Problems solved by technology

[0005] However, the cost of using capacitors to reduce the switching rate of the signal state is too high and the process is complicated, which is not suitable for mass use in manufacturing. Therefore, it is necessary to provide a low-cost high-speed signal transmission architecture suitable for manufacturing

Abstract

The invention includes a driving circuit module, a receiving circuit module, a main transmission line for connecting the driving circuit module and the receiving circuit module, and a micro strip structure connected between the driving circuit module and the receiving circuit module. The driving circuit module includes a driving circuit and a first transmission branch line used for transmitting signal output from driving circuit to the main transmission line. The receiving circuit module includes a receiving circuit and a second transmission branch line use for receiving signals from main transmission line and sending it to receiving circuit module. The micro strip structure functions like a capacitor. When the signal state in driving circuit module switches too fast, the micro strip structure is used to substitute for capacitor to decreases switching rate of signal.

Description

【Technical field】 [0001] The invention relates to a signal transmission technology, especially a technology for transmitting high-speed signals through a bus while maintaining the integrity of the high-speed signals. 【Background technique】 [0002] Under the action of the electric field, two conductors are coupled to each other. This coupling caused by the electric field is represented by mutual capacitance in the circuit model. There is mutual capacitance between any adjacent conductors. The closer the distance between the conductors, the greater the coupling. will be tighter. Similarly, under the action of a magnetic field, two conductors are coupled to each other, and this coupling caused by a magnetic field is represented by mutual inductance in the circuit model. Mutual capacitance and mutual inductance are the sources of interference. Mutual capacitance interference is manifested by mutual capacitance injecting a certain current at the crosstalk point on the victim l...
