摘要：

The performance of high-speed biomedical systems is adversely affected by switching noise caused by inductance in the power supply distribution network. In a high-speed medical system, signals are switched at rates up to 5 Gbps and discrete capacitors are ineffective in reducing the noise at this rate. The noise may affect patient care. Integrated plane coupling effectively minimized simultaneous switching noise by creating high capacitance between the planes. Although the suppression of electromagnetic interference due to switching noise on the component and printed circuit board is difficult, the integrated plane coupling at the front-end of the design cycle was shown to eliminate noise. The effect of switching noise coupling was investigated and a solution is reported. A test board was analyzed and the results were compared with simulations. This approach was shown to be effective in minimizing switching noise in high-speed biomedical systems.
