Unit 3 Integrated Circuit 集成电路 Part One Electronics Preparing for the text: Technical terms: 1. electronic counter 电子计数器 2. frequency synthesizer 频率合成器 3. digital instrument 数字仪器 4. operational amplifier 运算放大器 Questions for text discussion: What functions can integrated circuits perform? Perform function in digital systems and in linear systems 2. What type of elements may integrated circuits possibly include? Transistors, diodes, and resistors etc. 3. Tell some advantages of using integrated circuits. Sharp size, and weight reductions, low cost . The main idea of this unit: This unit mainly discusses the basic knowledge about Integrated Circuit. (1) Integrated circuit is a combination of a few interconnected circuit elements such as transistors, diodes, capacitors, and resistors produced in a single manufacturing process on one and the same bearing structure, called the substrate, and intended to perform definite function involved in converting information. (2) ICs can be classified by function into two: circuits to be applied in digital systems and those to be applied in linear systems. (3) The invention of IC is a great revolution in the electronic industry. Sharp size, weight reductions are possible with these techniques; and more importantly, high reliability, excellent functional performance, low cost and low power dissipation can be achieved.
