Problems solved by technology
Part of the clock signal distorts during the transmission process. This is due to the parasitic effect of the pins of the drive unit 100, which makes the high-frequency clock signal produce spikes at the pins of the drive unit 100 when passing through the drive unit 100. Causes waveform distortion of the clock signal
The waveform distortion will affect the electronic devices to varying degrees, especially in the high-speed electronic transmission circuit, laying hidden dangers for the normal operation of the electronic devices

Embodiment Construction
[0017] As we all know, in reality, every pin in IC chip has parasitic effects such as parasitic inductance and parasitic resistance, which makes when the frequency of the signal source is high, high-speed signals will be generated when passing through the pins with parasitic effects. Spikes are distorted. The system and method of the present invention can effectively change this situation.
[0018] The invention provides a system for improving waveform distortion during signal transmission. The system includes a clock signal source and a receiver electronic device. Wherein the interconnection length between the clock signal source and the electronic device at the receiving end is the transmission distance of the clock source signal in a quarter cycle. The system also improves the situation for non-clock signal sources.

Description
【Technical field】 [0001] The invention relates to a system and method for electronic signal transmission, in particular to a system and method for improving waveform distortion in the signal transmission process of electronic devices. 【Background technique】 [0002] At present, as the operating clock frequency of electronic devices is getting higher and higher, higher requirements are put forward for the interconnection (interconnection) between electronic devices. [0003] As we all know, due to the characteristics of the current integrated circuit (IC) manufacturing process, there are inevitably various parasitic effects (parasitics) on the pins of any electronic device, such as resistance parasitic effects, capacitance parasitic effects or inductive parasitic effects. Due to the existence of these parasitic effects, if handled improperly, high-speed signals will generate spikes when they pass through the pins of the device, resulting in waveform distortion of the signal. ...
