1、电子线路CAD课程设计报告题目标准电流信号转换成电压信号的电流/电压转换器设计学号班级学生指导教师年标准电流信号转换成电压信号的电流/电压变换器设计一、设计任务在工业控制中各类传感器常输出标准电流信号4~20mA，为此，常要先将其转换成±10V的电压信号，以便送给各类设备进行处理。这种转换电路以4mA为满量程的0%对应-10V；12mA为50%对应0V；20mA为100%对应+10V。二、任务要求(1)单面或双面板设计；(2)最小线宽：40mil（100mil=2.54mm）；(3)PCB板尺寸尽可能小；(4)电源、输入、输出必须有接线端子；(5)PCB布局整齐合理，布线规则美观。三、电路设
