摘要

物聯網是一發展中的無線傳輸應用，係指在網路化的時代下，除了人與人之
間可以透過網路相互聯繫、人也可透過網路取得物件的資訊外，物件與物件之間
也可以互通的網路環境。物聯網代表著未來資訊技術在運算與溝通上的演進趨
勢，而這樣的演進過程將會需要各種各樣領域的技術及科技創新來帶動，使得該
應用的發展面向小從奈米科技、大至城市無線網路的佈建，無所不包，影響十分廣泛。ZigBee 是物聯網發展中眾多通訊標準之一，其物理層與媒介存取控制層是依據IEEE 802.15.4 規範，具有低速、低耗電量、低成本、低複雜度等特點，相當適合當今物聯網以及綠能無線電發展的趨勢。
射頻前端電路是無線收發系統中距離天線最接近的主動電路。一般而言，射頻前端電路包含有低雜訊放大器、功率放大器、混波器、通道選擇濾波器等，對於系統中的量測參數如雜訊、線性度等具有決定性的影響。本論文使用離散電晶體實現一功率放大器與低雜訊放大器，性能要求盡可能接近德州儀器公司(Texas Instrument, TI)所生產之CC2591 射頻前端積體電路之性能。

The Internet of Things (IoT) is a wireless application under developing for communication between people and objects, which means that people or objects can communicate and get information from each other. The IoT is an evolution in operation and communication for human beings and objects, and this new technology of communication needs the integration of many techniques in engineering. For example, the IoT applications can be deployed from nano technology to wireless network provisioning in a city. One of the most popular standards for IOTs is the ZigBee, which defines the network and application layers in the basis of the PHY and MAC layers
specified by the IEEE 802.15.4 standard. ZigBee is suitable for the IoT and green ICT applications by the characteristics of low data rate, low power consumption, low cost and low complexity.
In this thesis, the main goal is to design a font-end for the IEEE 802.15.4 system with low power consumption. A low-noise amplifier and a power amplifier were implemented to achieve this goal with power consumption of 11.1 mW and 192.9 mW, respectively.
