双极性输出数模转换器教学探讨

Study the Method of Teaching Bipolar Output DAC

针对双极性输出 DAC这一教学难点 ,分析了自然二进制码、2的补码和偏移二进制码之间的关系及 DAC电路 ,推导出电路输出与输入关系表达式。最后用

It is discussed for teaching that the relation between binary, twos complement and offset binary code, then DAC circuits are analyzed and transfer functions are deduced. PSPICE simulator testified Conclusions.
