摘要: | 近年來,隨著人們依賴通訊系統的程度提高,使得通訊速度以及製作成本成為很重要的課題。所以,我們期待多頻操作來增進通訊效率,以及多頻整合的硬體來降低製作成本。然而,目前金氧半場效電晶體的特性,依然受制於許多製程上先天的缺陷,像是寄生效應。因此,金氧半導體電路設計,仍是一深具挑戰的研究課題。
本篇論文,為達到多頻操作,及節省面積的目的,提出了一系列創新的電路架構。在第三章中,利用共用電感的概念,提出一個節省面積的雙頻傳送/接收開關。在第四章中,藉由切換匹配方法的技巧,可使雙頻低雜訊放大器在節省面積的情況下,雜訊指數獲得改善。 Recently, with raises of communication system demand, communication speed and production cost turn out to be vital issues. As a result, multi-band operation to enhance the communication efficiency and multi-band combination to lower the production costs are expected. Unfortunately, the development of CMOS circuits has been long impeded by inherent shortcomings such as parasitic components. It is still a challenging task for designers to realize CMOS circuits near the transistor cutoff frequency. In this thesis, to operate in multi-band in an effective chip area, novel circuit topologies are developed for dual-band operations. In Chapter 3, an inductor-reconfiguration technique is introduced to the dual-band T/R switch, thus the single inductor can be reused in the transmitting and receiving modes. In Chapter 4, by switching the matching circuit, the noise figure of the dual-band LNA can be improved in a small chip area. |
