CMOS反相器和传输门的教学实践

摘要

CMOS inverter and transmission gate are the basic logic gate circuits in digital logic design and its application.They are also the digital circuits with which students first come into contact.Correctly understanding the inverter and the gate is the basis of learning other logic gate circuits.From the question existed in NMOS inverter to the formation of CMOS inverter and transmission gate, heuristic and discussion-based teaching method is applied in the course teaching.The process of problem solving is presented by guid-ing the students to analyze problems step by step.The practice results have shown that students’interest in learning the course has been improved,and that the knowledge of context and the related knowledge of mutual relations have been mastered.%CMOS反相器和传输门是数字逻辑设计及应用课程中最基本的逻辑门电路，也是学生最先接触到的数字电路，对它们的正确认识是学习其他逻辑门电路的基础。从NMOS反相器存在的问题，到CMOS反相器和传输门的构成，在教学中采用启发式和讨论式教学方法，逐步引导学生如何分析和探究问题的解决过程。学生提高了学习课程的兴趣，把握了知识的来龙去脉，掌握了相关知识的相互关系。
