在飞思卡尔智能车竞赛中电磁信号是分析判断赛道路径的重要依据。针对赛道提供20KHz交变电磁信号，本文提出了基于AltiumDesigner10和OPA2350的电磁信号采集电路板的设计。电磁信号采集电路板以OPA2350为核心，将20KHz交变信号进行放大设计；电路板原理图和PCB的设计采用AltiumDesigner10软件进行。结果表明：利用AlfiumDesigner10软件设计的电磁信号采集电路板能对20KHz交变信号进行正常放大，为后级信号处理系统奠定了基础。

In the Freescale Carle smart car race, electromagnetic signal is an important basis for analyzing and judging track path. In order to provide 20 KHz alternating electromagnetic signal for the track, this paper presents the design of electromagnetic signal acquisition circuit board based on Altium Designer 10 and OPA2350. The electromagnetic signal acquisition circuit board takes the OPA2350 as the core, amplifies the 20KHz alternating signal, and the circuit board schematic diagram and the design of PCB are carried out by the AltiumDesigner10 software. The results show that the electromagnetic signal acquisition circuit board designed by AlfiumDesigner10 software can amplify the 20KHz alternating signal...
