Development of the Measurement Tool and Impedance Test Method for the Signal fidelity in PCB Tracks

PCB 트랙의 신호충실성을 위한 임피던스 계산 방법 및 측정 툴 개발

As digital systems continue to use components with faster edge rate and clock speeds, transmission of the digital information can take place many troubles. The increasing requirement for controlled impedance PCBs becomes both a critical success factor and a design challenge. Especially, the noise sources in digital system include the noise in power supply, ground and packaging due to simultaneous switching of signal, signal reflections and distortions on single and multiple transmission lines. This paper simulates the tracks controlled impedance with the test coupon. So, it can saves the design time and supports the economical PCB design.
