逐次逼近型模数转换器原理实验方案研究

Successive Approximation Analog-principle Experiment Scheme

为了帮助学生深入理解逐次逼近型模数转换器这一教学难点,文中设计了逐次逼近式A/D转换器实验配合理论教学。实验包括基础和进阶两部分内容:基础实验采用串行10位数模转换器(D/A转换器)TCL5615设计逐次逼近式A/D转换器;在进阶实验中要求学生采用双路D/A转换器方案实现高精度A/D转换器,引发学生独立思考,在设计过程中培养其创新意识和创新能力。

In order to help students in-depth understanding of the successive-approximation ADC difficulty of teaching, the paper designed the successive approximation A/D converter experiment with theoretical teaching. Experiments including ba-sic and advanced two parts:basic experiments serial 10 DAC (D/A converter) TCL5615 design successive approximation type A/D converter;require students to advanced experiments using dual D/A converter program to achieve high-precision A/D converter, causing students to think independently, to develop their sense of innovation and ability to innovate in the de-sign process.
