In this thesis, we introduce RF transceiver architectures for the wireless communication system and some parameters of the down-conversion mixer. By means of the noise model of RF-CMOS mixers presented by ABIDI in 2000, circuit designers will know how the noise appears at the output of a CMOS down-conversion mixer.

本篇论文介绍了无线通讯系统中常用的射频接收机系统架构及混频器的参数介绍外，并藉由ABIDI於2000年所提出CMOS混频器之杂讯模型，透过此模型将使电路设计者更清楚的了解到杂讯源将经由何种过程出现在混频器的输出端。

CAN bus has been the most promising fieldbus and it has been widely used in many areas, but with the increasing of complicacy in automation systems for industrial controlling, people have more and more strict requirement to the real-time capability of information, So it is very important to study the real-time characteristic of CAN protocol for surmounting the limitation of aptotic priority in CAN protocol by taking effective measures and improving the real-time characteristic of communication system based on CAN bus.

CAN总线是目前最有前途的现场总线之一，它已经在多个领域得到了广泛的应用，然而随着工业控制自动化系统复杂性的增加，对信息实时性的要求越来越高，因此，研究CAN协议的实时性问题，采取合理的措施克服CAN协议中固定优先级机制的缺陷，提高CAN总线通讯系统的实时性具有重要的应用价值。
