dc.description.abstract | 隨著無線技術的迅速發展與普及,現今人們對資料傳輸需求量日益增大。無線區域網路由於能夠隨時隨地提供即時的多媒體傳輸服務,因此受到相當大的關注。因此,現今的研究著重於在各式各樣不同的使用環境中,提供良好的傳輸品質。
為了建立更加可靠與穩健的無線通訊連結,在本論文中,提出兩種自動增益控制迴路以擴展接收器的動態範圍。在第三章節中,功率偵測器引入了偏移抵消技巧,使得低雜訊放大器的增益能夠適應性地切換,因而進一步地避免了射頻前端電路進入操作飽和。第四章節中,以所提出之可程式化增益放大器為基礎,建構了一個具有自動增益調整功能之寬頻可程式化放大器,而此寬頻操作適用於現今與未來不斷拓展頻寬的無線區域網路規格。 | zh_TW |
dc.description.abstract | With the rapid development and popularization of wireless technology, nowadays people show ever-increasing demand for mass data transmission. Among all wireless local area network (WLAN) technology has attracted most attention due to the capability of real-time multimedia sharing anywhere anytime. Therefore, it is desirable to provide an excellent service quality for various environments.
In this thesis, in order to build up a more a reliable and robust wireless link, two architectures of automatic gain control (AGC) loop at both RF front-end and baseband are proposed for extending the dynamic range of the receiver. In Chapter 3, a power detector with offset cancellation is introduced for determining the gain mode of variable-gain low-noise amplifier. The gain selection mechanism prevents RF front-end circuits from operating in saturation. In Chapter 4, based on the proposed programmable gain amplifier gain (PGA) cell, a wide-bandwidth PGA with AGC function is constructed. The wideband operation meets the requirement of expanding channel bandwidth in new/ongoing WLAN standards. | en |
