基于Proteus的单片机模数转换电路的设计与仿真
|
摘要
以单片机控制A/D转换器TLC549为例,对A/D转换器的主要技术指标进行了分析研究,在Proteus平台下,完成了A/D转换电路的构建,采用器件工作时序方式进行程序编写,借助仿真图表、虚拟仪器等工具对A/D转换的数据进行测量并对失调误差、增益误差、微分非线性、积分非线性和转换时间等重要参数进行了详细分析。结果表明:使用Proteus软件可对A/D转换过程进行定性分析,将抽象的A/D转换器技术指标直观化、形象化展现出来,有助于学生更好地理解A/D转换过程。
The main technical indicators of A/D converter were analyzed and studied with an example from A/D converter TLC2543 which is controlled by using SCM. It was completed the construction of the A/D converter circuit under the Proteus software. The programming based on the operation sequence of the chip is put forward. With the aid of the simulation tools such as virtual instrument,simulation charts provided by Proteus,the important parameters of circuit such as offset error,gain error,differential nonlinearity( DNL),integral nonlinearity( INL) and conversion time are analyzed detailedly. Simulation results show that the A/D conversion process can be qualitatively analyzed and visualized the abstract indicators of A/D. The system can help students better to understand the SCM conversion process.
